Hi @adrtorre , thanks for reporting, and apologies for the long delay. This looks more like an issue in LocalStack itself, not related to the Serverless plugin. Can you help us and provide a small example configuration, so we can replicate the issue end-to-end?
Also, we've made a number of enhancements in the meantime - can you please double-check if the problem persists after pulling the latest Docker image? Thanks!
I'm having the same issue with a Chalice app when I try to redeploy/update an lambda. Upgrading to the latest version (1.1.1.dev) doesn't seem to help. I have to completely shut down localstack and restart in order to deploy a new version of my lambda.
Updating lambda function: my_app-local-my_function

Thanks for reporting @adrtorre @dhay - can you please share the details of your function configuration. Is your Lambda function configured with Lambda layers, by any chance? Would be great if you can share your client code / configuration, to make it easier for us to replicate the issue.. Thanks!
Hi again @dhay @adrtorre Closing this issue as resolved - according to our testing, this should be resolved with the latest version of the Docker image. Please do let us know if the problem persists.. Thanks!
