Can i make changes in the published version of aws lambda?

Question

Lets consider i have a lambda function , i have two versions of it v1 and v2 and both version are published If in any case i want to make code changes in v1 can i go directly to v1 and make code changes and publish the same version again?

Answer 1

Sadly you can't. Published lambda versions are immutable:

You can change the function code and settings only on the unpublished version of a function.

If your version is already publish, any changes must be made to a new version.
