Spotipo uses Flask-Migrate to keep the database up to-date , if there is a mismatch on the local migration scripts and this error is shown.
To fix this, follow below steps. _Remember to take a database backup just in case_.
- Delete the table called alembic_version from database.
mysql -u root -p -e 'use spotipo; drop table alembic_version'
- Delete the migrations folder. Its kept in /usr/share/nginx/spotipo
rm -rf /usr/share/nginx/spotipo/migrations/
