After updating today to the build 3.6.0.beta2-latest ([bf4d07a89c](https://github.com/discourse/discourse/commits/bf4d07a89cc2854fbea5b7f9716bbafb92d94963)) I noticed this error in the logs. This is the first time I’ve ever seen this error. The last time this error was reported on the forum was in 2020.
How can I debug this further? What can cause this and what’s the impact? Everything appears to be running at the outset.

Looks like your topic didn’t find any takers, so nobody had any immediate ideas how to help you. Were you able to resolve your issue or did it go away by itself?

Well now I’m seeing this error in the logs related to sidekiq and redis - never seen this error before the latest upgrade

And this error is happening repeatedly, not a one off.

Is your site at all adversely affected? If not, I wouldn’t worry about this so much.

Ok. FYR, it looks like this error can cause sidekiq to stop working and is supposed to be fixed in a newer version of sidekiq but not sure if discourse needs to make changes to incorporate this fix in their API’s
