Describe your question in detail.

I am upgrading a module via an msafe txn (don't believe issue is with msafe) and getting a 1020 VMError, and not seeing / understanding what that means. Can someone help?

The changes I've made are modifying an internal inline function's function header, changing an import to not import a type, and modified logic within public functions... I believe all of these are allowed and upgradeable?

What error, if any, are you getting?

getting a type error, and getting this when trying to upgrade from an msafe multisig...

Which operating system are you using?

Windows

Which SDK or tool are you using? (if any)

Aptos CLI

modifying an internal inline function's function header
Do you mean modifying the parameter or return type of a function? That's considered as breaking change, you can only modify internal logic of any function
