Installing plug-in - problem

[grantboxer]

When I install the plug-in, I get the following error message.

Any thoughts?

Regards Grant Boxer

Couldn't load plugin 'qgis_stac' due to an error when calling its classFactory() method

ImportError: cannot import name 'validate_core_schema' from 'pydantic_core' (C:\OSGeo4W\apps\Python312\Lib\site-packages\pydantic_core_init_.py)

Same problem here... However it's a duplicate of #261

[lahm3d]

I have a quick fix that solves the issue in short term. I modified pydantic import to pydantic.v1 and installed the plugin manually. It works on QGIS 3.40:

main...lahm3d:qgis-stac-plugin:custom and here's the zipped qgis_stac plugin
