Hi @Vaibhav Lonkar Greetings! Welcome to Microsoft Q&A forum. Thank you for posting the question here. We would glad to assist you with the request.

To update Azure Digital Twins using Azure Digital Twin Connector in Logic Apps, you would need to provide a JSON patch in the request parameter. Please find the below Request details I have set to the Update Twin method to perform a patch update.

Once I have the Json Patch set in the request, running the Logic App using the trigger would result in a successful update. Please find the below response from the method after the logic app is run.

If you still see the same, please confirm if you are able to perform any other Tasks with ADT connector such as fetching Digital Twin or Creating a Digital Twin. Please note that there is known limitation with Azure Digital Twin connector where we need to explicitly parse the JSON to the model before consuming it. Please let us know if you are trying to parse any data or provide input to the Update Twin method through a variable which might be causing this issue.
