My Domain classes are the same of the Grails 2.3.5 project.
I'm using the mongodb plugin.

Cannot reproduce this, please upload an example that reproduces the issue

[hemavidal]

This issue was resolved!

[hemavidal]

The problem was in Grails + MongoDB + GMongo(Excluded in grails 3)

[hemavidal]

I Added a declaration: def mongo in each Controller/Service that uses GMongo API.

[rkimaoui]

Hello hemavidal,
Which Gmongo version do you use ?
I can't make it work with: Grails 3.1.11 and mongodb:5.0.10 and com.gmongo:gmongo:1.5

[hemavidal]

Thats right now!
I've declared the gmongo separately.
Thanks!
