Hi,

I'm trying to upload the file to SharePoint using HTTP request. But getting following error. Tried with other possible solution but not resolving it.

Internal : Could not execute code stage because exception thrown by code stage: The 'Content-Type' header must be modified using the appropriate property or method.
Parameter name: name

It is generating token correctly and able to download the excel file but while uploading the same file getting this error.
can someone please help on this to fix it.

also as alternate solution @SukanyataiKawale

You can use graph API connector for SharePoint for working on SP folder and structure. below is the connector. you need to be ready with tenant id, client id, secret ID. Use upload file with necessary input.

you have to use content type as "application/octet-stream"
