    Hi RZidaj,

     

    Thank you for reaching out to Microsoft Fabric Community.

     

    Here looks like the issue is related to Dataflow Gen2 handling the Issues column as text during the refresh, while the function is actually returning a table.

    So please try explicitly keeping the column type as table and avoid returning null. Please try this below query:

    Table.AddColumn(#"Filtered Rows", "Issues", each try fnGetAllIssues([Project Key]) otherwise #table({}, {}), type table)

     

    Also please check and remove any automatic changed type step for the Issues column if present.

     

    Thanks and regards,

    Anjan Kumar Chippa
