Problem description

Describe what you did in console that led to the error. Please provide a description of what actually happens. Be descriptive: “it doesn’t work” does not describe what the behavior actually is. This will help us with reproducing the problem.

Steps to reproduce

Please describe steps to reproduce starting from the first action.

  1. go to Mission: GEO EXPLORER, import required zip file
  2. I can see the map with the locatino ponits, so the info is there
  3. Select schema tab

This is the message that pops up: " Opps! Something went wrong. [Report a problem]" and this doesn’t go away, even if I click other tabs such as home button or “Users” or “Manage” etc. only if I hard refresh.

Please help as I want to complete my missions!

Hello @Ilayda_B

Welcome to our community and thank you for trying out Backendless.

First of all, sorry for the inconvenience. I was able to reproduce the problem.
A ticket has been created for the development team to fix the problem. This ticket has the highest priority for us. We will notify you as soon as the problem has been fixed.
For reference, the ticket ID is BKNDLSS-27756.

As a workaround, I can suggest that you replace “visual-modeler” with “table-editor” in the link of the page where the error is reproduced.



Thanks so much for the speedy reply. Your suggested workaround works, so at least I can complete the mission. Thanks for looking into it!



Hello @Ilayda_B

We’ve just updated cloud servers with a fix for the issue you described above. Could you kindly let us know whether fix works for you well?


Hi @Inna_Shkolnaya,

Yes I can confirm that it now works for me! Thanks so much for the quick fix!
