ERROR Failed to create 999 response- X12 file validation

[jasirmuhammad]

I have got an issue while validating an X12 EDI file through command line.
TypeError: a bytes-like object is required, not 'str'.
Also help me to do this validation through python console.

The command I'm using is: x12valid <path> --verbose

Which line in which source file is throwing the error? Can you post the full traceback?

Using Python3 v3.8.5 on Windows... when running x12valid.py (v2.3.3) specifically, down stack in x12file.py, any line with:
self.fd_out.write(out) results in "TypeError: a bytes-like object is required, not 'str'".

Hack to force self.fd_out.write(bytes(out, encoding='ascii')) opens up a can of worms in downstream processing as there is bytes to string conversion needed if the hack is applied - so that is not the simple fix.

I am still debugging - but I assume that wherever x12valid.py code calls x12file.X12Writer - the "src_file_obj" needs to have the correct mode as tempfile._TemporaryFileWrapper. If anyone who knows the code base better can suggest the quick fix, I can try it and apply and do a pull request. Otherwise, given extra time (aka boredeom) and/or an urgent need to get x12valid working - hopefully can figure it out.

In x12valid.py, making this change:
- fd_997 = tempfile.TemporaryFile()
+ fd_997 = tempfile.TemporaryFile(mode='r+')
seems to work.
