Troubleshooting

There are different ways a PDF is generated, sometimes they may not work with Distill. In case they do not work, you will see an error in the check log with an error code. Following are the common error codes and the ways to troubleshoot them.

  1. ERR_PDF_PARSE error is usually encountered when Distill is able to download the file but fails to parse it. This usually happens when the file is either not a PDF file or is in a format that is not supported by Distill. You can wait for a few checks to see if Distill is able to download and parse it correctly.
  2. E_DOWNLOAD implies that the PDF file download didn’t complete successfully. This can happen when the download is interrupted and could not be completed. Distill will automatically retry.
  3. E_PDF_UNKNOWN_TYPE is encountered when Distill tries to download the file but the website doesn’t send one. This usually means that either the file is not a PDF file or the website didn’t send one. This can happen for different reasons. For example, the website can choose to block requests or require cookies before letting one download the file.

If the error persists after a few checks, please email us at support@distill.io.

PDF files are large, checking and diffing them consumes more resources. The cost of a PDF monitor is accounted for as checks in the account. 1 PDF check is counted as 2 checks.
