I’m receiving a timed-out error in Revit 2024.3 using Pollination 2.283.6.0. I’m not receiving this error in Revit 2025. See attached log.

Hi @mdouglass, this is caused because of a dependency issue with some other add-ins that you have installed.

We recently removed the dependency to System.Text.Json since this is becoming too common of a problem. Here is the version that should resolve this issue:

[Linked Removed]

If you can’t install the new version of the plugin, then try to unload other dependencies, and that should resolve the problem.

P.S. I just want to say how much I appreciate you documenting the issues carefully, and providing us with the additional documents. Thank you for uploading the logs to this post. :slight_smile: :folded_hands:

Installing 2.284.5.0 resolved the issue. Thanks!
