I also encounter the same problem when using latest 1.2.0. Below is my setting:  Below is the error in the superset logs when opening the "Upload CSV" page:  I checked the put request that sent to the backend for enabling csv upload: `https://{superset_url}/api/v1/database/13` In the request payload, the parameter "schemas_allowed_for_csv_upload" in `extra` was incorrectly set. It will cause `schemas_allowed_for_csv_upload` gets json parsed into string type instead of list type (source code in `superset.models.core.Database.get_schema_access_for_csv_upload` function). `extra` in the request payload in my case: `"{\"metadata_params\":{},\"engine_params\":{},\"schemas_allowed_for_csv_upload\":\"[\\\"superset_upload\\\"]\"}"` and after json parsing : `>>> json.loads("{\"metadata_params\":{},\"engine_params\":{},\"schemas_allowed_for_csv_upload\":\"[\\\"superset_upload\\\"]\"}") {'metadata_params': {}, 'engine_params': {}, 'schemas_allowed_for_csv_upload': '["superset_upload"]'}` You can see `schemas_allowed_for_csv_upload` became a string instead of list. And it will raise the error `TypeError: can only concatenate str (not "list") to str`  ```python def get_schema_access_for_csv_upload( # pylint: disable=invalid-name self, ) -> List[str]: allowed_databases = self.get_extra().get("schemas_allowed_for_csv_upload", []) if hasattr(g, "user"): extra_allowed_databases = config["ALLOWED_USER_CSV_SCHEMA_FUNC"]( self, g.user ) allowed_databases += extra_allowed_databases return sorted(set(allowed_databases)) ``` -- This is an automated message from the Apache Git Service.
