The following error message is produced:

Error: No file in D:\a\che-che4z-lsp-for-cobol\che-che4z-lsp-for-cobol matched to [**/pom.xml], make sure you have checked out the target repository

The problem seems to be due to the failure of the require('path') and the fallback to sep: '/' on the line 37866:
