I’m submitting a…

  • Regression (a behavior that stopped working in a new release)
  • Bug report
  • Performance issue
  • Documentation issue or request

Current behavior

Updating the version number from 7.9.0 to 7.10.0 in our Terraform scripts produces NullReferenceException and don’t let us fetch content or schema information.

Expected behavior

The migrations will be executed proper and all APIs work fine.

Minimal reproduction of the problem

  • The Version 7.9.0 is installed at Kubernetes with a MongoDB Database
  • Update to version 7.10.0
  • Try to show content in admin inerface

Environment

  • Self hosted with docker
  • Self hosted with IIS
  • Self hosted with other version
  • Cloud version

Version: 7.10.0

Browser:

  • Chrome (desktop)
  • Chrome (Android)
  • Chrome (iOS)
  • Firefox
  • Safari (desktop)
  • Safari (iOS)
  • IE
  • Edge

I think this is actually the same error. Would you be able to send me a backup of your database?

OMG. I have written a fallback serializer (because the format has changed slightly), I have written tests for that, but I have forgotten to register it :frowning:

4

Can you test squidex/squidex:dev-7836 If it works, I can publish a new release asap.

Hi,

thanks for the quick feedback

At 5pm CEST I am able to test the new version.

Hi Sebastian,

the selection of an actual schema of the schemas page works fine now.
But selecting one of the schemas in the content page fails with:

Hi,

it works fine now :slight_smile:
We can query all contents.

We will use your dev image until the new version is deployed.
Thanks for the fast support!

Kind regards
