Error occurred while uploading files to Foundation

Description

When submitting a file to Foundation from Winshuttle Studio, you may experience the following error: "Error occurred while uploading files to Foundation."

Applies To

Foundation, User Governance, Studio

Cause

If your script or data file size is excessively large (greater than 50 MB), it will cause a limitation in IIS to block the request.

Solution

If possible, try to reduce the script size or data file size. Sometimes, especially with data files given the amount of rows that can be transacted against, this may not be feasible. In that case, perform the following steps on each SharePoint server to increase the maximum file size allowed by IIS:
  1. Open IIS Manager.
  2. Navigate to the SharePoint web application IIS site.
  3. In the Features section, click on Configuration Editor.
  4. Under Section, select system.webServer > serverRuntime
  5. Increase the UploadReadAheadSize file seize from 49152 (bytes) to a value high enough to allow your data files. Raise the limit by an additional 10% to 20% if you foresee continuing submission of large data files.
