Hi there, I'm fairly new to odoo14 and I am getting this error while trying to build a new custom report.

ValueError: External ID not found in the system: account.account_tag_operating_activities

So, I created two new xml files with the respective menu and the respective tags to use, both .xml files are references in the manifest.py:

This is where the menu xml file:

xml version="1.0" encoding="utf-8"?>

    

        id="action_report_indirect_cash_flow" model="ir.actions.client">
            name="name">indirect cash flow
            name="tag">account_report
            name="context" eval="{'model': 'account.cash.flow.report.indirect'}"/>
        

        

        id="menu_action_reports_indirect_cash_flow"
                  name="indirect cash flow"
                  action="action_report_indirect_cash_flow"
                  parent="account.account_reports_legal_statements_menu"
                  groups="account.group_account_readonly"
        />

    

This is the tags file:

xml version="1.0" encoding="utf-8"?>

    noupdate="1">

        
        id="account_tag_operating_activities" model="account.account.tag">
            name="name">Cash Generated From Operations
            name="applicability">accounts
        

        id="account_tag_operational_free_cash" model="account.account.tag">
            name="name">Free cash flow from operations
            name="applicability">accounts
        

        id="account_tag_non_operational_cash" model="account.account.tag">
            name="name">Non operational cash flow
            name="applicability">accounts
        

    

Here is the custom model that I'm building:

# -*- coding: utf-8 -*-
from odoo import models, fields, api, _


class AccountCashFlowReportIndirect(models.AbstractModel):
    _name = 'account.cash.flow.report.indirect'
    _description = 'Cash Flow Report'
    _inherit = 'account.report'

    filter_date = {'mode': 'range', 'filter': 'today'}
    filter_comparison = None
    filter_journals = True
    filter_unfold_all = False
    filter_all_entries = False

    @api.model
    def _get_tags_per_account(self, tag_ids):

        tags_per_accounts = {}

        query = '''
            SELECT 
                DISTINCT account_account_id,
                ARRAY_AGG(account_account_tag_id)
            FROM account_account_account_tag
            WHERE account_account_tag_id IN %s
            GROUP BY account_account_id
        '''
        params = [tag_ids]

        self._cr.execute(query, params)
        for account_id, tags in self._cr.fetchall():
            tags_per_accounts[account_id] = tags
        return tags_per_accounts

    @api.model
    def _get_lines(self, options, line_id=None):
        tag_operations = self.env.ref('account.account_tag_operating_activities').id
        # tag_operational_free_cash = self.env.ref('account.account_tag_operational_free_cash').id
        # tag_non_operational_cash = self.env.ref('account_tag_non_operational_cash').id
        # tag_ids = (tag_operations, tag_operational_free_cash, tag_non_operational_cash)
        # result = self._get_tags_per_account(tag_ids)
        print(tag_operations)

So, my error is when I'm trying to get the id of any of the created tags I get the

ValueError: External ID not found in the system.

Any suggestion or idea on what I might be doing wrong? When I check the table accounts_accounts_tags I can see the tags that I've created, the same when I check ir_model_data table in my local database.

Any response is kindly appreciated.
