I’ve been frequently getting this error message the past 3-6 days.
It must have been due to a recent update.
It happens with old messages.
Here is the scenario:
We have some sort of a guideline shared via private messages with members if they’re interested in something. These kind of messages are evergreen and old. We’ve been adding members frequently to these messages.
We have few of these that we use the invite feature regularly on daily basis.
We’ve 10x checked the problem and the username is fine. I can actually add him to other messages just fine.
I had to copy the same message and send it to the user. It works just fine.
I could guess this happens with multiple old messages [Same error. Everything checked.] but not with newer group messages.
Would you like to make a screenshot of anything in particular that could help you debug this error?
