Descriptors cannot be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

I'm using the default workflow.

Ran ComfyUI and the nodes came up instead of being red. However, when I told it to run I still got:

I deleted all the GetVAE/connector wireless nodes & it progressed to the Sampler then bombed with

Guess I need to figure out where/how to get the Euler recognized/installed

I think your diffusers install is just outdated.
