SharePoint returning HTTP Status code 500 when posting files like png,pdf etc..

Hi Experts,

SharePoint returning HTTP Status code 500 when posting files like png,pdf etc.

Response body from SharePoint

<?xml version="1.0" encoding="utf-8"?>
<m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
<m:code>-1, System.IO.IOException</m:code>
<m:message xml:lang="en-US">I/O error occurred.</m:message>

</m:error>

Could you please help me with this.

Please find the screenshot attached.

I am hitting sharepoint URL through SAP Cloud Platform Integration middleware.

I am able to read file from Sharepoint in binary format and construct original file but when i try to post/upload file to Sharepoint i am getting below error.

Can you please help me if SharePoint expects any header other than Authorization while accepting binary files as i am able to post text files without any issue in code.

Hi @Sachin Belide ,

From the error msg, it seems to be related to a corrupted file IO. How do you read the file? Could you trace the request and share the complete request info? Have you added 'Content-Length' header? And will this error occur on other file types? What about uploading it through UI or an isolated request outside the cloud platform?

Best Regard,

Hi @Baker Kong-MSFT ,

I am able to upload file manually from UI and also using Postman.

Even after setting content length header,I am getting same error response from SharePoint.

Hi SachinBelide-7963 ,

yeah i think this error is not caused by the endpoint or sp server. It should be related to the runtime context. Is the pending file accessible when calling the request? There might be something wrong in file stream reading.

Since you're able to read file from SharePoint, I think you can try to read a file then directly pass the file stream to the post request.

Below C# demo reads file from an SP library and pass the stream to an item attachment. You may take a reference.

https://github.com/kongmengfei/sharedproject/blob/master/TeamifySharePointClassicSite/TeamifySharePointClassicSite/FileFormat.cs

If it works then I believe the exception happened in file reading.

Thanks

Hi @Baker Kong-MSFT ,
Thanks for ur reply.

I am able to read file content from Sharepoint in byte format and form the actual file and send it as an attachment in mail,but i am unable to post the same byte format data to Sharepoint as POST request which is throwing same HTTP Status code 500 Error as above.
