To reproduce:
2. Upload attached json (csv would do the same)
3. Observer internal server error
There's a chance my tool made json thats not compatible, but this is the first time of about 40+. - and if thats the case would be good to handle and return the problem.
We've had it working with both singletons and facsimiles - so not sure what's different here to cause this.
Cheers
