The errors appears only when i execute load fixtures with the three mentionned method : autoload, app.loadFixtures() or from terminal.

Thnakyou in advance for your help.

finaly i wrote my own boot script which reads data from a file and insert it in db. in your case try to call the script inside a boot script and your code to load fixutres inside
app.on('fire-connection-started', () => { app.loadFixtures() }

hope this will help

best regards
