error "/etc/my_init.d/500_check_db_access.sh failed with status 1" about overleaf

The MongoDB server has version 4.4.29, but Overleaf requires at least version 5.0

Like myself, you first have to update to MongoDB Version 5.0.

After doing so, I then had to force mongod to:

1. Bind to IPv6 localhost using mongod --ipv6
2. Enable support for transactions using a single node replica set by also adding --replSet rs0.

I also made sure to explicitly set the hostname for my MongoDB container (in my case overleaf_mongodb). Finally I had to initiate the replica set by running:

docker compose exec -it overleaf_mongodb /bin/bash -c 'echo "rs.initiate()" | mongosh'

If you don't set the hostname the rs.initiate() will create a replica set using the container ID, which will change, if the container is removed and restarted.

Just noticed that you cannot run MongoDB 5.0.

I'll leave my comment as the error may be quite frequent for users migrating to Overleaf Version 5.

Thank you for you quick answer. Your comment lets me consider runing Overleaf 4.2 instead of trying to deploy Overleaf 5. However, I think it is better to run Overleaf on some low-energy-comsuption devices such as Rasberry Pi so that one can TeX any time, any device with a very low environmental burden.
