Event METABOJECT_CREATE on "Forms" app

[mademilano1]

Hi,

for several months I used the following request graphql to create a webhook and register the data sent through the forms generated by the shopify app "Forms":

https://shopify.dev/docs/api/admin-graphql/2025-01/mutations/webhookSubscriptionCreate

As filter attribute I have always used: "type:app--6171699--shopify-forms12345"

Unfortunately for a few days this registration no longer works. I tried with different versions of api and different shopify accounts. The result is always

"The specified filter is invalid, please ensure you specify the field(s) you wish to filter on."

Can anyone give me some suggestions to solve? I would not want to give up the app "Forms".

Thank you.
