Hello, could someone provide some insight into why running
pulumi preview
on a brand new M1 Macbook which is configured (aside for maybe versions of tools) similarly to another machine on which everything works fine:
File "/Users/[REDACTED]/venv/lib/python3.9/site-packages/google/protobuf/", line 560, in __new__
TypeError: Descriptors cannot not be created directly.
If this call came from a file, your generated code is out of date and must be regenerated with protoc 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).
More information: <>
Using pulumi version 3.37.1 and python 3.9.13 On another box I'm using same python version and pulumi 3.34.1 and I do not encounter this issue. Any ideas if this could be pulumi version or could come from something else?

You need the right pulumi version and the right protobuf version, 3.36.0 regenerated the protobufs for python protobuf version 4.21
