Google Calendar sync duplicates meeting

[tothewine]

Hi,

I have an issue with Google Calendar sync in EspoCRM.

When I create an Meeting:

• it is correctly created in Google Calendar
• but a duplicate record is created in EspoCRM

So:
1 event → 2 records in EspoCRM

Configuration:

• Two-way sync
• Scheduled job active
• No workflows
• Fresh Google reconnection

Google shows only one event, duplicates are only in Espo.

Is this a known issue or am I missing something in the configuration?

Thanks

Greetings, tothewine,

Since I'm unable to reproduce this issue on my side after some testing, please provide more details regarding it.
- What Espo version are you using?
- What steps do you follow to catch this issue? Is there any additional settings are you using to create meeting or extra custom fields?
In any case, it's crucial to check the latest log file if you are using the self-hosted version, preferably with debug-mode enabled.

thanks for your reply.

Here are the details of my setup and how to reproduce the issue:

Environment:

• EspoCRM version: 9.3.4
• Google Integration: 1.8.4
• Outlook Calendar sync is enabled (two-way sync)

Custom setup:

• I created a custom entity called “Appuntamento”
• It extends the Event template:
  class Appuntamento extends \Espo\Core\Templates\Entities\Event
• No custom logic in:
  • Services (empty class)
  • Controllers
  • Hooks (none present)
• No active workflows or BPM processes

Steps to reproduce:

1. Create a new record in the “Appuntamento” entity
2. Save the record
3. Immediately after saving:
   • One correct record is created (with all data)
   • A second record is automatically created, but empty (no meaningful fields populated)

Important detail:
The duplicate appears instantly after save, without any manual action.

Additional checks already done:

• Disabled all workflows → issue persists
• Disabled Outlook sync temporarily → issue persists
• Checked custom code → no duplication logic found
• Checked DB table job → many jobs stuck in “Pending” (Google/Outlook sync included)

Relevant log errors found:

• Not a scheduled job
• Espo\Modules\Google\Classes\App\JobRunner does not exist

This makes me suspect there could be some issue with scheduled jobs or calendar integrations interfering, even if the entity is custom.
