I tried clicking Again but the same result. one more thing that I noticed is that when I rollback to the previous version( 0.37.6) then it works fine. but on 0.37.7 and even on 0.37.8 it shows the same message.
@danialakhter I mean that when you click Load the first time, and see the error, then try clicking Load one more time - or even a few more times.
Not sure what could be the reason why it’s not working on Heroku at all.
Check the log to see if there’s a more detailed error - Admin > Troubleshooting > Logs.
It makes sense that 0.37.6 works, since the code was changed in 0.37.7 to harden security.
@danialakhter
I think you would need to start your instance with debug logging in order to figure out why it’s failing, since I can make the URL work from my local instances without any problems, and only noticed a problem on a multi-instance, but I think that is caused by something else.
The 4th line from the bottom, which worked (PUT … 204). How did that succeed - a different URL or ?
