API Upload Fails Validation


This article explains the steps that should be taken to investigate a failed file validation when the upload occurred via API. While validation errors are explained clearly for user uploads, it can be slightly more obscure to identify the source of a validation error for API uploads, and this article is intended to outline the procedures for investigation.

Successful Uploads

Successful uploads are clearly visible in the UI when you navigate to Admin > Previous Uploads.

Unsuccessful Uploads

If an API upload fails validation (see this article for a general overview of validation), an email will be sent to the person who authorised the API upload, similar to the way that an error message is produced if an upload fails validation when uploading via UI. 

The following steps should be taken to investigate the error: 

  1. Log in to the FundApps environment the file has been uploaded to.
  2. Go to Admin > Previous Uploads 
  3. Find the specific upload you are interested in that has failed. Uploads that have failed validation will be highlighted in bronze.Previous_Uploads.png
  4. Click on this icon  on the right to show the validation errors by rerunning the API-uploaded file in the UI. 
  5. The next screen will show why it's failing validation and will help you identify what to change. Upload_Positions.JPG

This will give the full details of the properties which made the file fail the validation procedure, just as if the file was uploaded via the UI.


Q. I tried uploading a file but got the following error: "There was a problem validating this data file. Support has been notified, and we will let you know when the issue has been resolved." Now what?
A. While this is a blanket error, one of the reasons that could be causing the file upload to fail and receive this error may be the file size. The maximum file size is 11.4 MB when uploading via the UI. If your file is larger than this specified size, then compress the file and upload it as a ZIP file. In the Positions Upload screen, you can upload XML and ZIP files (CSVs are not allowed). The API is not limited to this file size restriction.

Q. Why can't FundApps not give this information in the API response?
A. The simple answer is security around sensitive data. At FundApps, we take security extremely seriously. As the validation errors could contain position-level information, we contain the API validation feedback in FundApps to ensure that only people with the appropriate permissions can see it.

Q. I received the following validation error when uploading a Portfolio file: "(invalid - The portfolio has an inception date beyond nav date)." What should I do?

Please provide a NAV Date, and this should resolve the issue.

Q. Can amendments be made to how files are processed upon discovering a validation error?
A. The way XML validation behaves upon discovering a file error is not something FundApps can amend because it uses a standard XML parser; however, please contact FundApps Support if you have any questions on validation failures.
