Pabbly connect workflow leakage

I have set up an automation using Pabbly Connect by creating a workflow where the trigger point is my Facebook Lead Ads form and the action point is Google Sheets. The workflow is designed so that whenever I receive a lead from my Facebook ad campaign, the lead details are automatically added to the Google Sheet.

However, after cross-checking the leads, I found that several leads are missing from the Google Sheet. Additionally, there are no errors being displayed in the workflow.

Hello @digitostechnologies,

Thank you for sharing the details.

We have checked the workflow you provided, and it appears to have executed successfully multiple times (around 7 executions from our end). There are no visible errors in the workflow history.

To investigate this further, could you please help us with the following:

1. Confirm if the shared workflow is the correct one where you are facing the issue.
2. Share details of the specific leads that are missing (e.g., email, names, or any unique identifiers).
3. If possible, provide screenshots or references from Facebook Lead Ads showing those leads.

Looking forward to your response.

Hello @digitostechnologies,

Thank you for sharing the lead details.

We have checked your workflow, and it appears that the form currently selected in your trigger has not received this particular lead at the time you mentioned.

Could you please confirm the following:

1. Have you made any recent changes to the workflow?
2. Have you changed the Facebook form selected in the trigger?
3. On which specific date were these changes made (if any)?

Looking forward to your response.

Yes, the lead I shared with you was received from a different form that was previously used in this workflow.

Thank you for your patience.

Our team has checked the backend logs for incoming Facebook leads. However, the specific lead you shared does not appear in our logs, which indicates that this lead was not received from Facebook on our end.

To investigate this further, could you please confirm:

• Whether this was a one-time occurrence, or
• If there are more leads that have been missed recently

Looking forward to your response.

Hi @Preeti Paryani
I am sharing you the screenshot of the leads with their ids and date which i have in my lead form but not in the sheet.

Ids are :- 1442287710910712, 877205142048024, 899175563152052

Also if you still can find the issue from your side, please schedule a google meet so that i can exactly show you the complete process and the leakage from the flow without showing an error.

Hey @digitostechnologies,

Thanks for sharing the details.

We have escalated this to our technical team for further investigation.

We’ll get back to you with an update soon.

Hey @digitostechnologies,

Thank you for your patience.

Our team checked the Facebook Lead Ads trigger logs, and it appears that the specific lead IDs you shared were never received from Facebook on our end. This indicates the issue is likely from Facebook’s side, as their system may occasionally fail to send leads and does not retry in such cases.

We recommend reaching out to Facebook support for further investigation on these lead IDs.

Please let us know if you need any further assistance.
