SQL error:may be the input source is a directory or a block device

• SQL Error

db_1       | ERROR: Can't initialize batch_readline - may be the input source is a directory or a block device.

sql_db_1 exited with code 1

 

• Cause

I changed the name of sql file. 😅  So it doesn't match with docker-compose file.

 

• Solution

Put the sql file name back as before.

And then docker-compose down, docker-compose up.
