Error 307 when insert new row


I have some trouble with inserting row. All time when I try to add row I have error 307 which is

    "message""The response is not in a JSON format.",
    "innerError""Cannot read server response."


What I'm doing wrong?


Thank you

Hi @ AlexFlok,



Could you please share a screenshot of the configuration of your flow? 

The error 307 is a temporary redirect error of http, please refer to the link and check if your issue could be fixed.


If you could provide more details about your scenario, we would provide a proper workaround for you.

Same issue. I setup flow from Gmail to Excel.

Please, help.

I am also having issue setting up similar flow from Gmail to Google Sheets (

That is why I decided to try Excel but having another issue. Is there any way I can setup reliable flow of e-mails to spreadsheets?


Is it possible to have delay between each e-mail flows? At least few seconds? I was wondering if each flow locks up table for a second or so making other e-mails flowing at the same time fail.

One of my users was having the same problem. The cause was lack of permissions to the SharePoint site that contained the SharePoint list affected by the flow. As soon as the user was added as a member to the SharePoint site, the error went away. I hope that helps.


Best regards,
