I used this issue to improve my aidevops cloudron subagent, and it managed to fix the issue on all instances. More info here for anyone interested to add this to your toolkit:

I have run the command
sed -i 's/\r$//g' /app/data/fix_db.shto fix the new line characters and then runbash /app/data/fix_db.shagain and it ran as expected. Disabled recover mode and confirmed things are back to working as expected.@ChristopherMag Thanks, this fixed my issue.

Hello @vaultwarden users
Since users have voiced their concerns about manually editing the database I have created a bash script that does it for you.
Please follow these steps if you have this issue:- create an app backup of your @vaultwarden Cloudron app
- put the erroring @vaultwarden app in recovery mode
- open the File Manager of your @vaultwarden app and create a
fix_db.shfile - copy and paste the following script into the just created
fix_db.shfile:#!/bin/bash echo "=> Checking if DEFAULT_CHARACTER_SET_NAME and DEFAULT_COLLATION_NAME are set to utf8mb4 and utf8mb4_unicode_ci" CURRENT_DEFAULT_CHARACTER_SET_NAME=$(mysql --silent --skip-column-names --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE} -e "SELECT DEFAULT_CHARACTER_SET_NAME FROM information_schema.SCHEMATA WHERE SCHEMA_NAME = '${CLOUDRON_MYSQL_DATABASE}';" 2>/dev/null) CURRENT_DEFAULT_COLLATION_NAME=$(mysql --silent --skip-column-names --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE} -e "SELECT DEFAULT_COLLATION_NAME FROM information_schema.SCHEMATA WHERE SCHEMA_NAME = '${CLOUDRON_MYSQL_DATABASE}';" 2>/dev/null) FIX_NEEDED=0 if [ "${CURRENT_DEFAULT_CHARACTER_SET_NAME}" != "utf8mb4" ] || [ "${CURRENT_DEFAULT_COLLATION_NAME}" != "utf8mb4_unicode_ci" ]; then echo "=> DEFAULT_CHARACTER_SET_NAME or DEFAULT_COLLATION_NAME is not set to utf8mb4 or utf8mb4_unicode_ci." echo "==> Current values are: DEFAULT_CHARACTER_SET_NAME=${CURRENT_DEFAULT_CHARACTER_SET_NAME}, DEFAULT_COLLATION_NAME=${CURRENT_DEFAULT_COLLATION_NAME}" FIX_NEEDED=1 else echo "=> DEFAULT_CHARACTER_SET_NAME is ${CURRENT_DEFAULT_CHARACTER_SET_NAME} and DEFAULT_COLLATION_NAME is ${CURRENT_DEFAULT_COLLATION_NAME}" echo "=> Nothing to do - quitting." FIX_NEEDED=0 exit 0 fi if [ ${FIX_NEEDED} -eq 1 ]; then read -p "Have you created a backup of your Cloudron Vaultwarden app?

Exiting." exit 1 ;; * ) echo "=> Invalid response. Please answer with y or n. Exiting." exit 1 ;; esac fi - open the Web Terminal of your @vaultwarden Cloudron app
- execute the following command:
bash /app/data/fix_db.sh - Execute the following command to start @vaultwarden:
/app/pkg/start.sh - Validate if your @vaultwarden is now working correctly
- If validated working, you can delete the
fix_db.shfile and disable the recovery mode of your @vaultwarden Cloudron app
If you run into any issues, copy the output of the terminal, post it here and restore your app from the backup created.

Hello @factord
This looks like a copy-paste issue from Windows.
\rin line 2 is a blank line, so a line break.
When you copy and pasted, it pasted the line breaks windows style.Please describe how you have copy and pasted the code into the
/app/data/fix_db.shfile. -

I just noticed TODAY that my VW was down. Thanks @james @christophermag for the fix. I also ran into the windows 11 copy/paste issue.
