I checked out v1.16.2 of the forum and was running node version 15.12 when I encountered the same error.
I downgraded to node version 14.6.0 and now this error is not coming up.

I hope this info can help anyone.

@rez0n I've just setup a NodeBB instance with the provided docker-compose.yml file from your repository. I've checked the log files at /usr/src/app/logs in the nodebb image, but can't find any credentials of the admin user in the file webinstall.log.
Do you know where I can find the credentials of the created admin account?
