Hello @Anmol ,
Welcome to out community forum!
And thanks for sharing the matter you observed after the upgrade.
On a quick research I found a previous post about it with some tips of what can be the cause and how to address it. Could you check Getting "ResponseError: The query parameter "pushRef" is missing" after updating n8n to version 1.41.0 and let us know if that would help?
If that does not help can you tell us more about the impact if you see any besides the message in the log?
We look forward to hearing from you!
Flavio
