HI All,

Could someone point me direction in troubleshooting for my problem?

I'm encountering errors while trying to activate the document_management_system and om_account_accountant-18.0.1.0.3 modules on a fresh installation of Odoo 18 Community. I have put the unzipped folders to custom-addons directory, modules appears in app list but i can not activate any module and getting the RPC Errors:

First Error:

Odoo Server Error

Odoo 18 Community Edition does not support certain fields like:

groups_id on ir.actions.act_window
users on res.groups

These fields were valid in older versions or the Enterprise edition but have been removed or refactored in Odoo 18.

1. Fix the groups_id Error (Act Window)

File:

accounting_pdf_reports/wizard/partner_ledger.xml

Problem Block:

<field name="groups_id" eval="[(4, ref('account.group_account_invoice'))]"/>

Fix:

Comment it out or remove it:

<!-- <field name="groups_id" eval="[(4, ref('account.group_account_invoice'))]"/> -->

2. Fix the users Field Error (res.groups)

Problem Block:

<record id="..." model="res.groups">
    ...
    <field name="users" eval="[(4, ref('base.user_root'))]"/>
</record>

Fix: Remove the users field:

<!-- <field name="users" eval="[(4, ref('base.user_root'))]"/> -->

3. Clear Odoo Cache and Restart

After editing the XML files:

# Stop Odoo
sudo systemctl stop odoo18

# Clear caches and compiled files
find . -name "*.pyc" -delete
rm -rf /opt/odoo18/.local/share/Odoo/filestore/YOUR_DB_NAME

# Restart Odoo
sudo systemctl start odoo18

Final Notes

These modules (document_management_system and om_account_accountant) are third-party, not official Odoo 18 CE modules.
Many community modules on GitHub or other sources may not yet be Odoo 18 compatible. You’ll often need to:
- Manually migrate them
- Test and remove deprecated fields
- Update manifest files

Error 1 – Invalid field 'groups_id' in 'ir.actions.act_window'

The groups_id field has been removed from ir.actions.act_window in Odoo 17+.
Removing or commenting that line eliminates the ValueError.

Error 2 – Invalid field 'users' in 'res.groups'

The users field is no longer allowed in XML (since it involves runtime objects).
Removing it from the XML file stops the error. You can assign users manually or through a post-init script in Python if really needed.

What You Must Do:

To be sure it works:

Edit the XML files (*.xml under /wizard or /security, depending on the error source).
Comment out or delete the lines with:

<field name="groups_id" ... />
<field name="users" ... />

3. Restart Odoo and update the module list.
