I'm attempting to load data from Cosmos DB via an ODBC connection. When I reference columns from a certain collection in my query, I get error messages like this:
DataSource.Error: ERROR [HY000] [Microsoft][Support] (50090) Conversion from string to number failed with value: 'Population Council IRB'
Which is kind of crazy, because I definitely want that column to contain text data. When I look at the schema that's being used in the ODBC connection, it does indeed say that the data is VARCHAR(255).
I tried to do a CAST on that column to get the error message to go away, and I also made sure to uncheck "Automatically detect column types and headeres for unstructured sources" in the Options menu. Neither of these resolved the problem. On some similar issues people have suggested making changes to the column properties in the Applied Steps, but because this is erroring out as soon as I try to initiate the query (i.e. my only Applied Step is "Source") I don't think this applies in my case.
Does anyone know how I might force Power BI to recognize this column as text and get the error message to go away?
Thanks!
