fastapi.exceptions.FastAPIError: Invalid args for response field! Hint: check that typing.Union[extensions.sd_dreambooth_extension.dreambooth.db_shared.DreamState, starlette.responses.JSONResponse] is a valid Pydantic field type. If you are using a return type annotation that is not a valid Pydantic field (e.g. Union[Response, dict, None]) you can disable generating the response model from the type annotation with the path operation decorator parameter response_model=None.

What is this? Help Thank You

Have not seen this before. Could be an incompatibility with the fastapi version you have installed. The webui recently pinned fastapi version to 0.90.1 (because there were issues with 0.91), but this extension pins it to 0.87.0.

What revision of the webui are you running? Maybe also post the info that is listed in the bug report template

[dilectiogames]

that is a good question, I can't seem to find how to check what version it is. yesterday I've used the git pull command and it said up to date so probably is the last version.

[Arilziem]

Version info is part of the information block that is shown in the console when you start dreambooth (using the webui-user-dreambooth.bat that you copied into your main directory). Just post that block (as shown in the bug report template).

ok, I've checked in the webui for updates today and it said is behind, updated and restarted everything, the error doesn't show up anymore.

it did show up after update and reload UI but got away when restarting the whole thing. I don't know. I will post here if I see it back. Thanks for the help. :)

Great. :)

Yes, error messages after installing webui extensions are a thing (especially when additional dependencies are needed). The whole mechanism doesn't seem very robust. Restarting the webui usually resolves most issues.
