    Hi @sea19,

     

    The error is your JSON format, you can check your input in your Flow action.

    You can check your JSON format on the website:https://jsoneditoronline.org/.

    Also, you could share your Flow configuration so that we can better deal with your problems.

     

    Best Regards,
