Which exact Fabrik version are you running, how did you update/install?
What are you fileupload ajax settings, did you set a "chunk size"?

 

[farinacci]

fabrik 3.7 last update not from Github
chunk size is 8MB.
the error is only in the form whit ajax enable= true and ajax link = true

I'm not sure if this chunksize is working correctly (I can vaguely recall issues long time ago).
So do you really need it? (Default is 0)

If you don't set Joomla's error reporting to max you won't get notices (which are breaking expected JSON formats).
