Thanks for raising this issue, couple of questions/suggestions;

• I saw you are using SAM CLI by installing pip install, we highly recommend using our installers for MacOS (see: https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/install-sam-cli.html)
• Your template definition might have some issues, in that case can you run sam validate --lint to see if it is going to print any errors
• If sam validate can't detect the issue, can you send us an example so that we can re-produce the problem on our side?

[arturzangiev]

I have tried to use sam installation as per guide, but it didn't resolve the problem.
sam validate --lint validates template fine and find no issues with it
My template is below, but i have removed the values of env variables otherwise this is the template:

I believe this is fixed via PR #5477, which will be shipped in our next release.
