ORAS publishing errors not being fully displayed #1115
Description
Describe the bug
When publishing to an OCI/ORAS repo, a 401 bad credentials error is being truncated and lost. It manifests as ERROR! Unable to push <PYTHON EXCEPTION> 246 <class 'ValueError'>: Issue retrieving session url: {'errors': which is unhelpful as the actual error is missing.
When the actual error message is saved to a debug global, the missing information is present. So somehow somewhere it is being truncated.
^mtempdc(7463.984942,"errMsg")="ValueError(""Issue retrieving session url: {'errors': [{'status': 401, 'message': 'Bad Credentials'}]}"")"
To Reproduce
Unfortunately I've been unable to reproduce this so far.
Expected behavior
Python errors should be properly displayed to the user. 401, 403, and 404 errors should also maybe get special handling. (This would likely be a good workaround trying to reproduce the full error.)
System information (please complete the following information):
- IPM version: 0.10.6
- IRIS version: Unknown
- OS: Linux
- Docker or local: Docker
Dev notes
Look at the %IPM.Repo.Oras.PublishService class, especially the Push() and PushOras() methods.

Note that this truncated error messaging also occurs when an incompatible Python version is installed (because that will only throw warnings and not fail IPM install itself), and certain commands are run. In general we should properly propagate Python errors to the user.

To properly propagate python errors, we may want to consider moving all of our Language = python references to external .py files and use %SYS.Python since that is the recommended approach to using embedded python

Rough idea:
IPM .py files should be
<FileCopy>'d to/mgr/ipm/<version>/pythonand then IPM code calls into%SYS.Python.Importwith the constructed full pathisc-dchui commentedon May 19, 2026
Users keep bumping into very unhelpful python exceptions so priority of this should be bumped.
