error: Error: [[error:group-name-too-long]] on NodeBB Upgrade

After upgrading NodeBB from 1.13.x to 1.16.1 I received the following error after the first start of the NodeBB instance:

  → [2020/10/13] Create verified/unverified user groups...Error occurred
2021-01-16T13:12:18.178Z [4567/28540] - error: Error: [[error:group-name-too-long]]
    at Object.Groups.validateGroupName (/home/makesmartnodebb/example.net/src/groups/create.js:84:10)
    at Groups.create (/home/makesmartnodebb/example.net/src/groups/create.js:19:10)

    at process._tickCallback (internal/process/next_tick.js:68:7)
[cluster] Child Process (28540) has exited (code: 0, signal: null)

The key message was:

error: Error: [[error:group-name-too-long]]

So I used a MongoDB client - such as MongoDB Compass - to fix the displayed error.

At first I used following filter to get the config of NodeBB.

   {_key:"config"}

I found the config object with following Key/Value Pair:

maximumGroupNameLength: 15

I changed it to:

maximumGroupNameLength: 30

So I was able to start NodeBB again.

I think the created groups within the upgrade caused this error.

I just write this topic to help people who are searching for this error. This is the fix.
