construct.core.FieldError: expected 32, found 20

I always get the error "construct.core.FieldError: expected 32, found 20" What sholud i do ?

I just discovered that one possible cause is when you have sha-256 CodeDirectory blobs. In the codesig.py, at ApplicationSlot.get_hash() you have a hardcoded 000 of lenght 20, which is incorrect for sha-256, which is 32. length should depend on the hashing algorithm

I got the same issue with latest xcode

Same error after I change 20 to 32

Well I did something like

return '\x00' * (20 if hash_algorithm == 'sha1' else 32)

But also, this can be because the new entitlements blob is not handled correctly, I went past that. Check if the version of CodeDirectory is 20500.
You can check my fork and see if you still got the error. Sadly, while the error is gone in my case, the resulted IPA does not install on the device, so it is still work in progress
