Failed when call to Azure Function Apps on Azure Data Factory

I cannot call Functions in Azure Data Factory.
Every time I try, it shows that error:
Input Payload is invalid, validation result – ‘["Connector or activity name: xxxx_function, connector or activity type: Azure Function, error: The stream was already consumed. It cannot be read again."]’
This issue appeared in today morning. In the previous days, there are no problem.
I used Python for my Function Apps.

I tried : – renew Function key in Functions App and refill this value in Linked service to Azure Funtion.
But it isn’t working.
I would be so grateful if you would be willing to help. Thanks <3

    I encountered a similar issue a few hours ago, but in my case, it was with Azure Data Factory Script Activity rather than Azure Functions. All of the linked services that were supposed to connect to various databases suddenly stopped working, which caused multiple pipeline failures.
    It was some Azure issue and we raised a support ticket, but it was resolved in the meantime. Going to post the response later if it will be usefull.

    Try to check the formatting of input payload. I have created a default V2 HTTP triggered python function and calling it from ADF.

    You can refer to this documentation as well.

    My pipeline looks like below

    enter image description here

    Input payload–

    {
    "functionName": "http_trigger1",
    "body": {
        "name": "Afreen"
    },
    "headers": {},
    "method": "POST"
}

    enter image description here

    Output –

    {
    "Response": "Hello, Afreen. This HTTP triggered function executed successfully.",
    "effectiveIntegrationRuntime": "AutoResolveIntegrationRuntime (East US)",
    "executionDuration": 2,
    "durationInQueue": {
        "integrationRuntimeQueue": 0
    },
    "billingReference": {
        "activityType": "ExternalActivity",
        "billableDuration": [
            {
                "meterType": "AzureIR",
                "duration": 0.016666666666666666,
                "unit": "Hours"
            }
        ]
    }
}
