https://sonarly.com/issue/26728?type=bug Workflow code steps fail when a Lambda function exists but is still in Pending state, because the build-status check only verifies existence and layer configuration without checking the function's readiness state. Fix: Prevent Lambda invocation while function is in Pending state checkLambdaExecutorBuildStatus() returned canSkip=true for Lambda functions in Pending state because it only checked existence and layer configuration, not Configuration.State. When canSkip=true, buildLambdaExecutor() skips the lock entirely and never calls waitFunctionActive(), so execute() invokes a Pending function → 409 ResourceConflictException. This race is triggered when concurrent workflow steps (Promise.all in executeFromSteps) hit the same Lambda while it's being created or updated by another invocation. checkLambdaExecutorBuildStatus() — line 987 Added lambdaExecutor.Configuration?.State === 'Active' to the canSkip condition. This ensures the build is only skipped when the Lambda function is fully Active. If the function exists but is Pending/Inactive/Failed, canSkip will be false, forcing the caller into the locked ensureLambdaExecutor() path which calls waitFunctionActive() or waitFunctionUpdated().

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
