NX Passed 11161 file paths to Git to hash, but received 11148 hashes.

Current Behavior

This is effectively a re-open of : https://github.com/nrwl/nx/issues/8779

After upgrading

• node from 14.16.1 to 16.14.2
• npm from 6.14.12 to 8.5.0
• nx from 13.8.0 to 13.10.3

I have frequent builds on my Jenkins builds failing with errors like > NX Passed 11161 file paths to Git to hash, but received 11148 hashes.

Expected Behavior

• The hashing should log the error returned from git hash-object e.g. fatal: Cannot open 'xxxx': No such file or directory
• If the hashing fails builds should not fail - i.e. the build should proceed nx caching disabled

Steps to Reproduce

Have not seen the pattern that causes these errors to occur The proposed improvement in “Expected Behaviour” will not solve the problem but will

• provide more info that could make it possibly solve the error - e.g. from https://github.com/nrwl/nx/issues/8779 one solved the problem by adding a directory with temporary files to .gitignore and this might also be a solution to my problem, but which directory ??
• mitigate the effect of the problem by allowing the build to complete albeit without caching

I think you have to run git hash-object and add the folder with the error to .gitignore.

I think you have to run git hash-object and add the folder with the error to .gitignore.

thank you! I found out that the error happens as soon as I generate files outside the Nx scope (in my case a build from pkg) that’s recognized by git. As soon as I add these files to .gitignore the problem is fixed.
