Power Apps "Error when trying to retrieve network: Expression "SKU eq null" is not supported"

[Anonymous]

Hey,

Im quite new to Power Apps and when Im performing below formula Im seeing this error.

I cant seem to figure out what's causing the error. I am working on this formula so that when I have a selection from PowerBI, it will input the comments that I have.

So for example when I click on the table for Jan2021, it will update the "Comments" column.

Thanks!!

On this particular occasion the Power BI integration did not send data back to PowerApps, and therefore there is no data in the "SKU#" field. Go back to Power BI, make sure your PowerApps visual gets data, and then edit the app again.
