Had a similar issue. Saw the recommendations in https://community.powerbi.com/t5/Desktop/We-cannot-convert-the-value-null-to-type-Table/td-p/391064, and after upgrading my PowerBI version the error was resolved.
Hi,
Have you solved your problem? Because we also met the same problem when trying to load table to power bi using direct query from the clickhouse odbc. The table have no null values but power bi always give that "We can not convert the value null to type table". So I think maybe the same problem with you.
Great thanks if you have suggestions
We're getting the same error as mvarma with the Impala connection. However, the DQ connection to Impala worked properly in workbooks we created in the past, and such existing workbooks still function properly. But if we create a new worbook and try to create a new DQ Impala connection, we get this same 'null to type table' error. A preview of the table successfuly renders in the data/query step, but we cannot "close and apply" without encountering the error. We did just update to Power BI Desktop to 2.54.4970.961, so perhaps a bug introduced in a recent release? It had been a few months since our last update to PBI Desktop.
Share more information if convenient. You may check each step in The Advanced Editor.
I am trying to upload a table from impala to PowerBI. From the GetData button I choose impala and then connect to the impala and choose the database and then the desired table and click load. And it tries to load the table and fails with the error message "We cannot convert the value null to type table". I tried opening up the "Edit Queries" button and loading the table from there by clicking the apply and close button once the table is opened in editor, there also the same error appears. This is not specific to table, I tried several table and the same error appears.
Appreciate your help on this at the earliest.
