JSON Error reading Arcgis online feature layer.


Badge

When reading an Arcgis online feature layer I get this message. It has worked before and there are no problem with other feature layers: 

Python Exception <JSONDecodeError>: Expecting ',' delimiter: line 1 column 10367918 (char 10367917)

I'd suspect that FME is getting an incomplete response, either due to network issues or it is just too much data. Can you reduce the Features Per Request parameter and see if that helps?

Yes, I've tried that. Even reduced to 5 or 1 the reader stops with error after reading some feature (approximately from 80 to 1000). It can't be a network problem. I get the same error at home and at work.
