Redmine

Hi,

since last upgrade to 5.1.3, I have this error each second in the production.log file:

E, [2024-07-24T08:58:58.322470 #727368] ERROR -- : WebSocket error occurred: wrong number of arguments (given 2, expected 1)
E, [2024-07-24T08:58:58.702001 #727359] ERROR -- : WebSocket error occurred: wrong number of arguments (given 2, expected 1)

Here are details about my env:

I have absolutely no idea where to look and why this error?
It didn't exist in version 5.0.5...

Many thanks for your help.
