Post with array input cannot have lambda in function stack?

JG

I have a POST endpoint that is ingesting webhooks from a third party (wrike). The payloads are a single array like this:
[
{
"title": "Follow up on status of RFI with Architects",
"taskId": "IEACIWZSKQZGQVIU",
"oldValue": "Follow up on status of RFI with Architect",
"eventType": "TaskTitleChanged",
"webhookId": "IEACIWZSJAABNRYU",
"eventAuthorId": "KUAEW7KF",
"lastUpdatedDate": "2023-03-05T20:48:17Z"
}
]

When anywhere in my stack i try to do a lambda step, i get the following error: ["$input must be an object"].

My lambda code is not part of the error, i've set the code to: return "John Doe";.
It seems like the lambda is expecting the $input parameter to always contain an object, which is not always the case with webhooks.

Is there any way to fix this?

Why don't you check first if the "Get All Input" result is an object or not with the filter "is_object". If it is false, just create an object containing whatever the result was. Then do the lambda step.
