import failed when we try to import mybb into flarum dockerized

[costalfy]

Hi,
I run Flarum into a docker container like this
I export my mybb database and i imported all datas in the same database as flarum.
When i used your latest plugin i have this error message :
"Oops! Something went wrong. Please reload the page and try again." without any other precission in log files into my mariadb container
I have try to change the value of host field to the ip of my container or the name of my container but nothing happened and same issue appears
How can i debug the process to solve my problem?
Best regards

Is the mistake it caused by the backslash before mysqli in the migrator.php?
