The 'content' property of actions of type 'ParseJson' must be valid JSON. The provided value cannot be parsed: 'Unexpected character encountered while parsing value: S. Path '', line 0, position 0.'.

    The error tells us there is an unexpected character is S at position 0, which means the Parse JSON action is receiving plain text, not JSON, as its input. To diagnose where that S is coming from, we need to see the actual value being passed into the Parse JSON content field (for example, the output of the previous action). Without that input, it’s not possible to identify the root cause. Check the Parse JSON for a stray S somewhere.

    The error occurs because the Parse JSON action is receiving plain text instead of valid JSON.
     
    The input must be a properly formatted JSON object (starting with { or [), but your current input starts with a regular string (e.g., “Status…”).
     
    To fix this, verify the actual input using a Compose action, ensure the source returns valid JSON, or modify your flow to either convert the text into JSON format
     
    or avoid using Parse JSON when the input is not structured data.
