We have two custom modules written for Odoo 15, each with their own models. To make things simple and avoid sharing too much information, we'll call them process and tank. A process can have many tanks, but a tank can only have one process. I used a Many2one and One2many field relationship between tanks and processes, and I've shown the field definition lines for each file below.
Whenever I upgrade either the tank parent module or process parent module, I get the error shown below, up until I push literally any commit to Odoo.sh involving the models' definition files. The error example shown below comes from the process parent module. I upgrade the module, and then get this error until I push ANY commit to Odoo.sh (which forces a reload in our case) involving the process.py file. I'm not quite sure of the root cause of the issue, and I've spent about 2 weeks off and on Googling and trying to solve this weird issue. The bandaid fix is enough for development environments, but this application goes live soon so I'd like to get it taken care of.
This is the field definition line from the process.py file. The model name is process:
tank_ids = fields.One2many('tank', 'process_id')
This is the field definition line from the tank.py file. The model name is tank:
process_id = fields.Many2one('process', 'tank_ids')
Below is the full error traceback:
