Odoo 13: How to solve CacheMiss Exception

Question

I'm working on generating a .docx document on Odoo 13, I checked the "report_py3o" module but there is no version for Odoo 13 so I decided to some kind of migrate (I just deleted the "@api.multi") the Odoo 12 version to Odoo 13. I got an error like odoo.exceptions.CacheMiss: ('ir.actions.report(85,).is_py3o_report_not_available', None) and my database was corrupted. Here is the full log : error log.

odoo.exceptions.CacheMiss: ('ir.actions.report(85,).is_py3o_report_not_available', None)

I also checked the aero module but it is avaible for 8.0 and 9.0 only.
Can you help me? Do you have alternative for me?

I haven't watched into it, but a CacheMiss is usually thrown, when a computed field method isn't computing a value for every record it gets.

Wrong:

computed_char_field = fields.Char(compute="_compute_computed_char_field")
some_boolean = fields.Boolean()

def _compute_computed_char_field(self):
    for record in self:
        if record.some_boolean:
            record.computed_char_field = 'something'

If there are some records with some_boolean == False you will get a CacheMiss when calling them (in a list view for example)

Correct way is to always set a value, in this example just add an else branch:

def _compute_computed_char_field(self):
    for record in self:
        if record.some_boolean:
            record.computed_char_field = 'something'
        else:
            record.computed_char_field = ''
