Hello,
Welcome to the community!
Your error pretty clearly states the problem - you are trying to make a GET request with object ID ‘1377368480714228’ which does not exist, cannot be loaded due to missing permissions, or does not support this operation.
Please attach a screenshot of your Facebook module’s configuration (blur sensitive data!). Without it, we won’t be able to help you.

I don’t have a solution but wanted to raise awareness for this issue that is still not resolved and seems to affect multiple different Webhooks that have something to do with Facebook.
@Dmytro_F is having issues with a post-module. For me, the “New Lead” module is triggering with the same error.
Similar to them, I also had a lot of these modules running in the past and didn’t change any settings - now none of them work anymore and give out the “[400] The HTTP request that was sent to the server has invalid syntax." - error.
I reconnected my Credentials, made sure that make is in the Business-Integration and have proper permissions on page and lead form. I also made sure to recreate different webhooks for different pages and different forms, creating new scenarios and updating old scenarios. None of them work.
A similar problem has been reported in the forums in July 2025 here Facebook Lead Ads - broken down in between?
And in September 2025 here Facebook Lead Ads - All scenarios stopped pulling new data (Unsupported get request)
This user is also getting the same error, January 2026: Graph API question
There are various other threads in the community forums of people recently getting GraphAPI error because the ID / object “does not exist, cannot be loaded due to missing permissions, or does not support this operation.”
In most cases, the issue was on Meta’s side and them messing with the GraphAPI and the required permissions. If that is the case again, the issue needs to be forwarded and escalated between Make and Meta to fix whatever is going on and make the integration functional again.

Hi everyone,
I’m having a strange issue with the Make Facebook Lead Ads module and wanted to check if anyone
has seen the same case.
In my case, the Meta webhook itself seems to be delivered successfully. The Lead Ads Testing
Tool shows that the webhook payload is sent to Make, and the payload includes the expected
leadgen_id, page_id, and form_id.
However, after Make receives the webhook, the Facebook Lead Ads module fails when it tries to
retrieve the lead details by leadgen_id.
The error is:
[400] Unsupported get request. Object with ID does not exist, cannot be loaded due to missing
permissions, or does not support this operation.
GraphMethodException (100)
What makes this confusing is that the scenario starts normally, waits for data, receives the
event, and then fails inside the Facebook Lead Ads module before any next module runs. So the
issue is not coming from my email, Telegram, CRM, or later scenario steps.
I’ve already tried the usual troubleshooting steps:
- Reauthorized the Facebook Lead Ads connection in Make
- Removed and re-added the Make app in Facebook Business Integrations
- Checked and reset Leads Access / CRM access
- Confirmed page/form/user permissions
- Created a new Facebook Lead Ads credential
- Created a new module
- Created a new scenario
- Re-selected the Facebook Page and Lead Form
- Tested with another Facebook admin account
- Tried Watch Leads as an alternative trigger
The same error still happens.
Meta Support told me they don’t see an issue on Meta’s side. Also, some other Facebook Lead Ads
scenarios are still working, so it doesn’t look like a complete Facebook account-wide outage.
Has anyone run into this exact situation where the webhook is delivered, but Make fails
afterward when retrieving the leadgen_id?
I’m trying to figure out whether this is a Make connector subscription/cache issue, a page/
form-specific Leads Access issue, or some Meta-side permission state that is not visible in the
normal UI.
Any real-world workaround or fix would be appreciated.
