Helper IHow to solve Query Parameter error?
Hi Pmorg-73 ,
It is telling you which parameter to look at: Parameter12.
In Power Query, go to the Home tab > Manage Parameters and all your parameters should be listed here:
It looks like you have a parameter that, for whatever reason, isn't getting populated before you're trying to refresh. It may be the result of another query that isn't refreshing in time before the main query requires it, but difficult to say from here, I'm afraid.

Thanks for posting in the Microsoft Fabric Community.
As already shared by BA_Pete , the error is pointing to Parameter12, which likely isn't returning a value at the time it's being used during refresh. In many cases, this happens when a parameter relies on a query that hasn't loaded or has returned an empty result.
From similar reports, this error can also occur if a query is operating on an empty list or table, especially during transformations like pivot or list functions. Another possible cause is duplicate column names while pivoting, which can lead to structure issues during refresh.
It’s best to check in Power Query which query is dependent on Parameter12, and then step through the applied steps to see where it breaks. Also ensure that any related query loads successfully before the parameter is used.
