Maya USD v24 error: "Could not open asset for reference introduced by"

[sharktacos]

Describe the bug

In Maya USD v24 when I run this code to create a payload with the API:

def add_payload(prim: Usd.Prim, payload_asset_path: str, payload_target_path: Sdf.Path) -> None:
    payloads: Usd.Payloads = prim.GetPayloads()
    payloads.AddPayload(
        assetPath=payload_asset_path,
        primPath=payload_target_path 
    )

I get an error:

# Warning: In </asset>: Could not open asset @f:/shared_assets/USD/test/asset.usd@ for reference introduced by @f:/shared_assets/USD/test/asset_payload.usda@</donutThree>. (recomposing stage on stage @f:/shared_assets/USD/test/print_payload.usda@ <0000016FB2416CA0>)

I do not get this error in Maya USD v23.1 with the same code. So it appears that this is something particular to v24

If anyone has any ideas as to what may be going on, I'd be most appreciative!

Workaround: Reverting back to v23

EDIT: I think this may have something to do with how Maya-USD is writing relative path names. The above code writes them like this:

prepend payload = @./foobar_payload.usda@</foobar>

Maya (using the context menu in the Outliner) is writing them like this:

prepend payload = @foobar_payload.usda@

and FWIW, if I edit my USDA files and remove the "./" they read fine in Maya with USD v24.

I hope that is useful info. Frankly, this is all above my pay grade to sort out what's going on here!

Specs (if applicable):

• Windows 10
• Maya 2024.1
• Maya USD v24

Closing this issue. The problem was not with Maya USD, but instead with my API code. I resolved this and everything is working as expected.
