Lambda was not able to unzip the file

Question

The file worked up until recently when updating a lambda however it started showing the following error:

Calling the invoke API action failed with this message: Lambda was not able to unzip the file

I thought it might be because it is hitting the limits but the shaded jar is only 24.3 MB

I think it may be a corrupted jar however I don't know enough about maven to ensure it isn't a corrupted jar.

Any ideas on what I should do to fix/debug?
