Help Needed: Invoke HTTP Request - "Not a JSON Format" Error in Flow

Hi everyone,

I need some assistance with an issue I'm facing in my flow. I'm working on a flow to retrieve an SSRS report from Dynamics 365 Field Service and email it through the Field Service. Initially, the flow was functioning well. The only error I encountered was with the Invoke HTTP action while downloading the PDF. To resolve this, I used a "Do Until" action to keep it in check, which worked after 1 or 2 runs.

However, suddenly, the first Invoke HTTP action, which was previously working fine, broke. Despite trying multiple times and even creating a new flow, I can't seem to get it to work again. The error message I'm receiving states that the response is not in JSON format.

Here are some additional details:

  • The flow was originally working without issues.
  • The error appears to be related to the first Invoke HTTP request.
  • I used the "Do Until" action to handle the previous errors, but this approach doesn't seem to work for this new issue.
  • I've attempted to create a new flow from scratch, but the problem persists.

If anyone has experienced a similar issue or has any advice on how to resolve this, I would greatly appreciate your help!

Thank you in advance for your assistance.

    Have you simply use do while loop to try a few times?
     
    your screenshot shows you retry once only

    @nsl coder  The Flow failed on the Invoke Http request.
     
    It is giving error.
    Note: It was working fine earlier suddenly it stopped working.

    What you provided isn't enough info to troubleshoot the error.
     
    Please provide info on which action failed, and the input / output from that action and previous action where the action that failed has dynamic content depended on it.
