Hey

i'm running into a problem with the PDG service example:
$HH/help/files/pdg_examples/top_mayapipeline/mayapipeline.hip

Does anyone has an idea what could be the issue here?

I tested it with maya 2022 and maya 2024.

Getting the issue: 
[16:38:37.646] ERROR: Failed with:
Traceback (most recent call last):
  File "C:\Users\Jonas\AppData\Local\Temp\houdini_temp\mayapipeline\pdgtemp\scripts\genericrpc.py", line 290, in _exec_script
    exec(compiled_block, l_dict, l_dict)
  File "<string>", line 6, in <module>
RuntimeError: Unsaved changes.


[16:38:37.646] ERROR: Task callback onCookTask failed

The issue might be because of running maya with an education version, but this has worked before tho.

Cheers
Jonas

The exception itself is coming from Maya. It looks like the API has change slightly in the last few versions. You should be able to replace the last two lines of the script with:

cmds.file( file_to_load.path, open=True, force=True)

instead of:

cmds.file( new=True, force=True)
cmds.file( file_to_load.path, o=True )

Current PDG does not support running Maya as a service out of the box, although the plan is to have that finished for H20.5. It would technically be possible to write your own custom Maya-based service and use it with the block in H20, which is why the option is still available on the block.
