Hello, I have a recurring error, when sls deploy on my project.

An error occurred: XXXXXLambdaFunction - The role defined for the function cannot be assumed by Lambda…

any idea?

I had no problem and suddendly, this happens. I have 30 lambda in a file.

Thanks!

That’s usually caused by an IAM issue, not a code issue. Did something change with your IAM roles?

If you look at the configuration for your Lambda functions, you’ll see the role that they’re trying to assume - is it correct? Does it have a trust relationship with the Lambda service (i.e. lambda.amazonaws.com)?
