Database connected but error: SQL Database Connector issue: No database selected

Hello everyone, my database is connected but impossible for me to run any query, I always have the error:

SQL Database Connector issue: No database selected

I’ve try:

SELECT iUserId FROM register_user WHERE vEmail LIKE ‘$1’ LIMIT 5;
And
SELECT * FROM register_user LIMIT 5;

But no one is working. Is someone have an idea ?
Thanks

I’m also having the same issue. I verified that Bubble can connect to the database, but for some reason I can’t get an INSERT INTO query to work - I get the same error message.

Is there a requirement to put a USE statement to specify a database into every query?
