I'm trying to create a Power Automate flow which takes a file from multipart form data received via an HTTP trigger and then creates this file within OneDrive or SharePoint.
I've found a few older tutorials online which have enabled me to get to the stage where I can access the multipart form data and convert the base64 encoded version of the file into binary. If I run my Power Automate flow with only these steps, then it runs successfully. However, as soon as I add an extra block to the flow to do anything, I get back an InvalidRequestContext error from the flow.
Here's the version of the flow which works:
The first Compose section has an expression of 'triggerMultipartBody(0)'. The second Compose section has an expression of '
The error I receive from this is:
I had the same problem.
What is more - if I delete the creation of file step - flow run with success.

The main reason for the error you get is that trigger "When a HTTP request is received" cannot receive any type but application/json. So in trigger leave JSON Schema empty.
The child flow:
The main flow which I trigger from the button is very simple:
The last step is to send a request to child flow.
In URI you should specify the URI from the trigger of the child flow.
Hi I can't get this to work. Can you please look over to help?
I am getting a mismatch type error for string and object. This is how my http call to child looks.
Can you look over the issue that i am still having with this? I feel like i have tried to duplicate but still getting a type mismatch error from the child flow.
Hi, I did forget the brackets but added it in but gets the same error message below. I am triggering this from postman using an .jpg file in the body. The JSON schema in the child i copied from this post. If i change the 'object' to 'string' there, i get over this error but fails in 1st in the child.
"The input body for trigger 'manual' of type 'Request' did not match its schema definition. Error details: 'Invalid type. Expected String but got Object.'. "
I have the same issue! With empty JSON Schema, I am getting "
