# Introduction
Avoid having a time window where the logic function is unavailable while
being built, by implementing an update flow instead of delete and create
everytime
fixes https://twenty-v7.sentry.io/issues/7371110591/
**Note: executor code propagation (pre-existing limitation)**
The Lambda executor shim
(`logic-function-drivers/constants/executor/index.mjs`) is only deployed
when a Lambda is first created. If this file is edited, the change won't
propagate to existing Lambdas — neither before nor after this PR. A
follow-up could compare the deployed `CodeSha256` against a local
checksum to detect drift and trigger a code update via
`UpdateFunctionCodeCommand`.
Should implem as code versioning or checksum diffing
