Description

Attachment cannot be uploaded when the file size is more than 2.99MB by using RESTFUL API. You will receive an Internal Server error 500.

However, the same attachment can be uploaded through the attachment fields in the UI.

Cause

The web.config file in the API subfolder (Archer website's virtual directory /Archer/api) has the default value in maxRequestLength and maxAllowedContentLength.

Resolution

Add or modify the maxRequestLength and maxAllowedContentLength values in the web.config located in the Archer website's virtual directory (/Archer/API).

<httpruntime maxRequestLength="400000" executionTimeout="3600"/>
