Loopback-next: 500 Error: The key repositories.UserRepository was not bound to any value

Created on 1 Mar 2019 · 3Comments · Source: strongloop/loopback-next

I'm getting this when using createBelongsToAccessorFor.

step 1- > i'm calling "http://localhost:3000/dealers/1/user" endpoint. (getting response correctly with data).
step 2 -> then i'm calling again "http://localhost:3000/dealers/1/user". I'm getting that error.
step 3 -> after restarting loopback server that api works correct.
Only first time after restarting server it works correct.
Please help me to fix this.

Unhandled error in GET /dealers/1/user: 500 Error: The key repositories.UserRepository was not bound to any value.
