Hi, we get AttributeError when pressing a button to change the state of an RFQ in our Odoo system while running this function:

def state_machine_trigger(self, trigger_name):
self.ensure_one()
proxy = Proxy(self, "state")
MACHINE.add_model(proxy, initial=self.state)
try:
proxy.trigger(trigger_name)
except MachineError as e:
_LOGGER.exception(e)
except Exception:
_LOGGER.exception("here be bork")
finally:
MACHINE.remove_model(proxy)





Traceback (most recent call last):
File "/home/odoo/odoo/lib/odoo/odoo/addons/base/models/ir_http.py", line 237, in _dispatch

if not subtype.exists():
Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "/home/odoo/odoo/lib/odoo/odoo/http.py", line 641, in _handle_exception
return super(JsonRequest, self)._handle_exception(exception)

raise exception.with_traceback(None) from new_cause
AttributeError: 'str' object has no attribute 'exists'

Yeah we discovered that the problem only occurs when adding tracking=True to the field. the subtype.exists() is being called in mail module that tracking uses, how do we fix our field so that we can use tracking? Thanks!

Thanks a lot for your answer, it works. I have been trying to migrate an odoo v12 module into v17, and the field parameter tracking_visibility seems to cause this subtype.exists() error.

here subtype.exists()  in subtype you are getting a string value not an object so you cant call subtype.exists()
