Hi,

When trying to upload images from onedrive business and into the Guides Images dataverse Table.

Please see screenshot.

I get the following error

A supported MIME type could not be found that matches the content type of the response. None of the supported type(s) 'application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=true, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=false, application/json;odata.metadata=minimal;IEEE754Compatible=false, application/json;odata.metadata=minimal;IEEE754Compatible=true, application/json;odata.metadata=minimal, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=full;odata.streaming=true, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatib...' matches the content type 'application/octet-stream'.

    Hi David,

    I found the same example and has not work for me. 

    I also believe base64string needs to be "base64string"

    Thanks,

    Michael

    BTW see you tomorrow at the webinar!

    Hi Mihail, this is not specific to Guides so you may get better traction posting to the Power Automate community at powerusers.microsoft.com/.../MPACommunity.

    Being curious I looked around and found these examples of people experiencing similar issues with content type mismatches during uploading. Most commonly I've found people recommending using a JSON Composer step to convert the image data into the following format:

    {
"$content-type": "image/png",
"$content":base64string
}

    Is this enough of a hint to investigate further? I look forward to hearing your results.

    Hi,

    Thanks for sending me this link.

    However I do get the same message as above.

    :A supported MIME type could not be found that matches the content type of the response...."

    Thanks,

    Michael
