fix(source-salesforce): Refresh Bulk API access token to prevent INVALID_SESSION_ID errors (AI-Triage PR) by devin-ai-integration[bot] · Pull Request #75201 · airbytehq/airbyte

What

Resolves https://github.com/airbytehq/oncall/issues/11700:

https://github.com/airbytehq/oncall/issues/11700

Long-running Salesforce Bulk API syncs fail with INVALID_SESSION_ID because the access token is captured as a static string at stream initialization and never refreshed. When syncs exceed the Salesforce session timeout (default 2 hours), all subsequent API requests fail.

How

Introduces a new SalesforceTokenProvider class that replaces the CDK's InterpolatedStringTokenProvider. Instead of storing a static token string, the new provider:

Holds a reference to the Salesforce API object
On each get_token() call, checks whether 20 minutes have elapsed since the last refresh (well before the default 2-hour session timeout)
If the interval has elapsed, calls sf_api.login() to obtain a fresh access token
Returns the current sf_api.access_token (which login() updates in-place)

The previous code at streams.py:533:

token_provider=InterpolatedStringTokenProvider(api_token=self.sf_api.access_token, ...)

captured self.sf_api.access_token as a string literal at construction time — it could never change.

Review guide

source_salesforce/streams.py — The only substantive change. Review the new SalesforceTokenProvider class (lines 72–93) and its usage (line 562).

Human review checklist (key risk areas):

TokenProvider ABC contract: is get_token() -> str the only required method? (No __post_init__ or dataclass concerns?)
Thread safety: login() is called without a lock. If multiple threads share this provider, concurrent refreshes could race. Is this a concern given how Bulk API streams use it?
Error handling: if login() fails (network error, invalid refresh token), the exception will propagate up to the caller. Is that acceptable, or should it be caught and retried?
No unit tests are included for the new class.
Changelog entry currently uses [TBD] as the PR number placeholder — needs updating before merge.

User Impact

Salesforce Bulk API syncs that run longer than the session timeout (default 2 hours) will no longer fail with INVALID_SESSION_ID. The token is proactively refreshed every 20 minutes. No user-facing configuration changes.

Can this PR be safely reverted and rolled back?

YES 💚

…LID_SESSION_ID errors Replace static InterpolatedStringTokenProvider with a new SalesforceTokenProvider that proactively refreshes the access token every 20 minutes (well before the default 2-hour Salesforce session timeout). This prevents INVALID_SESSION_ID errors during long-running Bulk API syncs. Root cause: The Bulk API declarative streams captured the access token as a static string at initialization time via InterpolatedStringTokenProvider, which has no refresh mechanism. For syncs exceeding the session timeout, requests would fail with INVALID_SESSION_ID. The fix wraps the Salesforce API object in a custom TokenProvider that calls login() to obtain a fresh token when the refresh interval has elapsed. Co-Authored-By: bot_apk <apk@cognition.ai>

Fix Validation Evidence

Outcome: Could not Run Live Tests — Regression tests passed; live connection testing blocked pending human approval for version pinning.

Evidence Summary

Regression tests completed successfully with no regressions detected. The pre-release version 2.7.19-preview.20cc051 was published and is ready for testing. Live connection testing could not proceed because the version pinning tool requires approval from an @airbyte.io team member, and the Slack escalation did not receive a response within the session window. The fix itself is sound: SalesforceTokenProvider refreshes the Bulk API access token every 20 minutes, directly addressing the INVALID_SESSION_ID errors that occur after the default 2-hour session timeout.

Next Steps

Unblock live testing: A human with an @airbyte.io email needs to approve via the Slack escalation or post an approval comment on the oncall issue
Once approved, pin the affected source actor to 2.7.19-preview.20cc051 and trigger a sync lasting 2+ hours
Alternatively, proceed directly to /ai-canary-prerelease for broader canary testing — the regression test results and code review strongly support the fix
The daily_hands_free_triage automation will monitor the release rollout after merge

Connector & PR Details

Connector: source-salesforce
PR: #75201
Pre-release Version Tested: 2.7.19-preview.20cc051
Detailed Results: https://github.com/airbytehq/oncall/issues/11700#issuecomment-4089804470

Evidence Plan

Proving Criteria

A Bulk API sync that previously failed with INVALID_SESSION_ID after ~2 hours completes successfully without session timeout errors.

Disproving Criteria

The same INVALID_SESSION_ID error persists after applying the fix, OR new errors appear that weren't present before.

Cases Attempted

Regression tests — PASSED. No regressions detected comparing pre-release vs baseline. (Workflow)
Live connection test (customer connection from oncall issue) — BLOCKED. Qualified candidate identified (not pinned, enabled, on v2.7.18, actively syncing). Approval for version pinning requested via Slack escalation but not received within session window.

Pre-flight Checks

Viability: Fix addresses the reported issue — new SalesforceTokenProvider class refreshes token every 20 minutes
Safety: No malicious code or dangerous patterns
Breaking Change: No breaking changes detected (no schema type changes, field removals/renames, PK/cursor changes, spec changes, stream removals, state format changes)
Reversibility: Patch version bump (2.7.18 → 2.7.19), can be safely downgraded/reverted
