ParserError exception raised for invalid configuration #2685
Description
search you tried in the issue tracker
ParserError and unicode
describe your issue
I executed pre-commit autoupdate with an invalid configuration file (the second - repo is indented incorrectly) and got this error message:
$ pre-commit autoupdate
An unexpected error has occurred: ParserError: while parsing a block mapping
in "<unicode string>", line 1, column 1
did not find expected key
in "<unicode string>", line 7, column 1
Check the log at /home/carsten/.cache/pre-commit/pre-commit.log
This is an expected error and I would expect an error message like `Your configuration file "..." is wrongly formatted at . Please review the format of the content.'.
Thank you,
Carsten
