…resh token rotation (#4735) * feat(zoom): add KB connector for cloud recording transcripts, fix refresh token rotation * fix(zoom): trim maxRecordings within page, relax VTT cue-id parsing * fix(zoom): widen incremental sync overlap to 30 days for late transcripts

* feat: add LiteLLM as AI gateway provider * fix: add litellm to attachments, provider store, utils, and block guards * fix: add frontend model discovery pipeline for litellm provider Add API route, contract, query hook case, and ProviderModelsLoader entry so litellm models are fetched and synced to the store on workspace load, matching the vllm/ollama/openrouter/fireworks pattern. Also fixes defaultModel to empty string and adds litellm/ prefix early-return in blocks/utils.ts (reviewer feedback). * fix: remove azureEndpoint fallback from LiteLLM provider Copy-paste artifact from vLLM provider. LiteLLM should only use LITELLM_BASE_URL, not fall back to azureEndpoint which could cause requests to be routed to the wrong server. * fix(litellm): close audit gaps from PR #4644 - byok.ts: add litellm branch to getApiKeyWithBYOK so workflow block execution can resolve the proxy key instead of throwing "API key is required for litellm ..." - check-api-validation-contracts.ts: bump route baseline 755 -> 756 to account for the new /api/providers/litellm/models route - .env.example: document LITELLM_BASE_URL / LITELLM_API_KEY - copilot edit-workflow validation: include LiteLLM in the list of user-configured prefixed providers shown to the model - providers/utils.ts: drop stray optional-chain on providers.litellm to match the vllm pattern - lint: apply biome formatting fixes (multi-line if, SVG path, multi-line DYNAMIC_MODEL_PROVIDERS) * fix(litellm): final parity gaps from second audit - blocks/utils.ts getModelOptions(): include litellm models in the combined model dropdown — was previously dropping any proxy-discovered models from the agent block model picker. - get-blocks-metadata-tool.ts mockProvidersState: add litellm bucket so the server-side copilot block-metadata fallback can render model options when the providers store is not initialized. - blocks/utils.test.ts: add litellm to mock providers state (initial + beforeEach reset) and add a parallel store-bucket guard test mirroring the vLLM case. - providers/utils.test.ts: add parallel getApiKey test for litellm. * feat(litellm): use official LiteLLM brand icon and color - icons.tsx: replace the placeholder letterform with the official LiteLLM brand mark embedded as a PNG data URI in an SVG image. - models.ts: set color: #040229 on the litellm provider definition to match the brand background. * chore(litellm): validate /v1/models response with shared schema in initialize() Match the API route handler — both code paths now run the same vllmUpstreamResponseSchema.parse() over the upstream /v1/models JSON instead of a raw type-cast, so malformed upstream payloads surface a descriptive ZodError instead of a downstream TypeError.

PR Summary

Medium Risk
Touches OAuth/token rotation, AI routing, HTTP error classification, and executor subflow/HITL paths—moderate blast radius but mostly additive fixes and integrations.

Overview
Release v0.6.91 bundles integrations, API behavior fixes, file-viewer UX, executor cleanup, and hosted API keys.

Zoom gains a knowledge-base connector for cloud recording transcripts, with refresh token rotation fixed so long-lived Zoom connections stay valid.

LiteLLM is added as an AI gateway provider, routing model calls through LiteLLM alongside existing gateways.

API errors now map access denied and sandbox user-code failures to the correct HTTP status codes instead of generic errors.

File preview zoom applies to viewer content (e.g. PDFs), not the whole browser page—addressing broken zoom on Zoom-related files.

The workflow executor sees subflow and human-in-the-loop handling refactors for clearer control flow.

Hosted keys add Hunter.io and People Data Labs so workspaces can use those enrichment APIs without bringing your own keys.

Greptile Summary

This release bundles six distinct improvements: a Zoom KB connector for cloud recording transcripts, LiteLLM as an OpenAI-compatible AI gateway, HTTP 422 classification for user sandbox errors, SVG file viewer zoom fixes, executor/HITL subflow cleanup, and hosted-key support for Hunter.io and People Data Labs.

Zoom KB connector (connectors/zoom/zoom.ts): windowed cursor pagination over the Recordings API, VTT parsing, incremental sync with overlap, and a concurrent fix enabling Zoom OAuth refresh-token rotation (supportsRefreshTokenRotation: true).
LiteLLM provider (providers/litellm/): full OpenAI-compatible provider with streaming, tool-call iteration, forced-tool sequencing, and a server-side models discovery route.
Executor cleanup (executor/execution/): edge keys migrated from an ambiguous dash-delimited string to a JSON array, deactivatedEdges and nodesWithActivatedEdge now persisted into pause snapshots and restored on resume, HITL resume outputs propagated into loop/parallel aggregation buffers, and getBlockOutput scoping rewritten for nested parallel branches.

Confidence Score: 5/5

Safe to merge; all changed paths have matching tests and the refactoring is isolated to the executor and connector layers.

The executor refactoring is substantial but is paired with extensive test coverage across edge-manager, engine, executor, and orchestrator files. The new Zoom connector, LiteLLM provider, and Hunter/PDL hosted-key additions are additive and follow established patterns. The error-classification fix (422 vs 500) and OAuth token-rotation fix are small, targeted corrections with clear rationale.

No files require special attention; the snapshot migration in edge-manager.ts (normalizeSerializedEdgeKey) and the HITL aggregation buffer update in human-in-the-loop-manager.ts are the most complex additions but both are well-guarded.

Important Files Changed

Filename	Overview
apps/sim/connectors/zoom/zoom.ts	New Zoom KB connector for cloud recording transcripts; well-structured with windowed cursor pagination, VTT parsing, incremental sync support, and proper error handling.
apps/sim/providers/litellm/index.ts	New LiteLLM AI gateway provider following the same pattern as other OpenAI-compatible providers; supports streaming, tool calls, forced tool sequencing, and cost tracking.
apps/sim/executor/execution/edge-manager.ts	Significant refactoring: fixes ambiguous edge key format (string → JSON array), adds deactivatedEdges persistence/restoration, unifies loop/parallel sentinel detection via subflowType/subflowId.
apps/sim/executor/execution/executor.ts	Adds edgeManager to buildExecutionPipeline, restores deactivatedEdges from snapshot, and registers cloned subflow parent maps for parallel branch resume correctness.
apps/sim/lib/workflows/executor/human-in-the-loop-manager.ts	Adds updateResumeOutputInAggregationBuffers to propagate HITL resume outputs into loop and parallel aggregation scopes, fixing stale outputs in nested subflow contexts.
apps/sim/executor/execution/state.ts	Rewrites getBlockOutput scoping logic to correctly resolve outputs across nested parallel branches using extractOuterBranchIndex and branch/loop suffix matching.
apps/sim/app/api/function/execute/route.ts	Changes user sandbox code errors from HTTP 500 to 422 for correct error classification; 422 is semantically appropriate for user code execution failures.
apps/sim/app/workspace/[workspaceId]/files/components/file-viewer/preview-panel.tsx	Replaces sandboxed iframe with blob-URL img for SVG preview; properly guards render with {blobUrl && ...} and revokes the URL on cleanup.
apps/sim/executor/execution/engine.ts	Passes edgeManager to snapshot serializer, calls handleNodeCompletion before pause processing, and correctly handles PARALLEL_CONTINUE in the stop-after-block check.
apps/sim/executor/execution/snapshot-serializer.ts	Serializes deactivatedEdges and nodesWithActivatedEdge into pause snapshots so they can be restored on resume.
