SharePoint Spoke File Size Limit

[Paul Kunze]

Hello all,

we are integrating SharePoint in ServiceNow by building a Flow that contains Flow Actions from the OOTB SharePoint Spoke.

The questions are:

• What is the allowed file size for the Flow Action "Copy Attachment To Folder"?
  
  • The official ServiceNow documentation does not mention any size. But we see that it must be really small because our 2 MB files are not getting transferred (small files work fine).
  • The Microsoft documentation mentions a limit of 250 GB so the limit will not be on that side.
• Can the size limit be configured or customized somewhere if we want to keep using the OOTB Spoke?
• What is a simple alternative if the allowed size is too low for our use case? I know that custom REST messages would be possible but we want to avoid big effort and complexity, especially because there is already a Spoke available.

Do you find any logs in the flow execution history?

@Paul Kunze  , check if this docs help you - https://www.servicenow.com/docs/bundle/zurich-platform-security/page/administer/security-center/refe...

You can increase the value in the system property - com.glide.attachment.max_size to allow maximum size of a file (in MB).

If my response has helped you, mark it as helpful and accept the solution.

Hi, thanks for the responses.

The system property "com.glide.attachment.max_size" has the default value of 1024 MB so this is not the issue.

Actually I just saw that the Flow is not triggered if the file is too big. I am first converting the whole file to Base64, then sending it via Ajax to the backend and processing the file using GlideSysAttachment. Is it possible that a Base64 string cannot contain several Megabytes?

var attachment = new GlideSysAttachment();

var attachmentSysId = attachment.write(grRecord, fileName, contentType, GlideStringUtil.base64DecodeAsBytes(base64EncodedContent));
