Thanks @Jeremyball - I can not seem to reproduce it here.

I think I know what the issue in the code - but your setup would need to confirm that. Can you share your configured "roots" for the project? Or provide the output printed from:

import ayon_api
from ayon_core.pipeline import get_current_project_name

print(ayon_api.get_project_roots_by_site_id(get_current_project_name()))

I have a feeling you have it configured with backslashes maybe, or with other 'special' characters that may be special to regex patterns.

It'd be nice if you can also attach a JSON Publish report from the Publisher UI (you can export that from bottom left in the publisher).

In the meantime, I'll prepare a potential fix.

[BigRoy]

@Jeremyball Here's a PR to test at least it passing this particular point: #64

---

However, looking at the code I think the 'matching' it tries to do against the filename will fail anyway (at least without error so you can still publish).
@antirotor and @Lypsolon would need to tell me more about how this should work.

At this point in the code the variables for me are:

dependency_info={'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset\\v007\\ynts_char_beast_usdAsset_v007.usd': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset\\v007\\ynts_char_beast_usdAsset_v007.usd', 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset\\v007\\payload.usd': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset\\v007\\payload.usd', 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset_model\\v003\\ynts_char_beast_usdAsset_model_v003.usd': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset_model\\v003\\ynts_char_beast_usdAsset_model_v003.usd', 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdMain\\v004\\ynts_char_beast_usdMain_v004.usd': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdMain\\v004\\ynts_char_beast_usdMain_v004.usd', 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset_rig\\v003\\ynts_char_beast_usdAsset_rig_v003.usd': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\usd\\usdAsset_rig\\v003\\ynts_char_beast_usdAsset_rig_v003.usd', 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\rig\\rigMain\\v004\\ynts_char_beast_rigMain_v004.usd': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\rig\\rigMain\\v004\\ynts_char_beast_rigMain_v004.usd', 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\rig\\rigMain\\v004\\ynts_char_beast_rigMain_v004.ma': 'c:\\projects\\ayontest\\asset\\char_beast\\publish\\rig\\rigMain\\v004\\ynts_char_beast_rigMain_v004.ma'}
root_info={'work': 'C:/projects'}
replacements={'C:/projects': 'work'}
pattern='(C:/projects)'

As you can see - the regex doesn't match it - and hence my pinning file does NOT contain rootless keys @Lypsolon @antirotor

---

Also @antirotor I'm quite sure we don't want the pinning file to be generated for EACH USD file, right? Only for renders? or?

[Jeremyball]

Hey, thanks for the quick response. Attached publish report

Print out:
{'work': 'E:\AYON\projects'}

publish-report-241004-09-22.json

[BigRoy]

{'work': 'E:\AYON\projects'}

Thanks, that confirms it:

import re

re.compile(r"E:\AYON\projects")
# Error: error: file C:\Program Files\Autodesk\Maya2025\Python\Lib\re\_parser.py line 438: bad escape \p at position 7

import re

pattern = re.escape(r"E:\AYON\projects")
print(pattern)  # prints: E:\\AYON\\projects
re.compile(pattern)

So my PR should at least allow you to continue - or if hard for you to update and deploy yourself, otherwise change your path in settings to use forward slashes, like: E:/AYON/projects.

[Jeremyball]

For now I will reconfigure with forward slashes. Thanks!

Edit: Confirming publish works as expected
