Unsupported query - using type: blob.

You are getting this error likely because the field you are running the query on does not exist on the layer or the layer view. Try setting the FeatureLayer.outFields property to include the fields you want to work with.

Seems like there's an issue with the queryFeatures query with outFields and type 'blob' 

I made a Codepen to reproduce it (check console.log). @UndralBatsukh

Hi there, 

Ah yes this is a known issue at 4.28. This issue will be addressed in 4.29 and the fix is already in `next`. You can update your codepen to point to  <script src="https://js.arcgis.com/next/"></script> to check the fix. 

Hope this helps,
