Hello. I'm Using Odoo17

I have been developing custom modules to use in a database hosted on Odoo.sh.
I have recently encountered an error: When I try to change the "version" property of the manifest of one of my modules (from 1.2 to 1.3), the build is successful in a dev branch but fails in a staging one.

The error I get from the platform is 

At least one test failed when loading the module (module name)

I have tried viewing the platform-integrated logs for more details but they don't seem to have any information on the error, and I can't replicate it anywhere else.
Any idea of what might be causing this? It is extremely specific and is only happening on one of the three modules I am developing.
The manifest file looks like this:
{ 
 "name": "Project extension", 
 "version": "1.3", 
 "summary": "Project extension", 
 "description": "Extension of Project module", 
 "depends": [ "base", "project", ], 
 "data": [
 "views/project_project_views.xml", 
 "views/project_task_views.xml", 
 "security/project.groups.xml", 
 "security/ir.model.access.csv", 
 ], 
 "application": True, 
 "installable": True, 
 "license": "LGPL-3",
}
