Splunk Enterprise Security

Splunk Enterprise Security: Why am I unable to find Threat Intellegence data after successful URL download?

Greetings and thanks for the looking at this question. I have a Splunk server in an air-gapped environment and I'm trying to get threat intelligence data from an external, Internet facing client to an internal URL server and then have Splunk Enterprise Security (ES) perform a URL download of the intelligence file. The external client downloads the feed and then pushes the feed to the URL server (I can push XML, JSON, CSV files).

I am able to get the intelligence file to the URL server from the external client and I set up a Threat Intelligence stanza within Data inputs » Threat Intelligence Downloads to download the file via URL. I am also able to verify that the intelligence file is successfully downloaded; here are the logs for the download:

Then after the file is downloaded, I am getting the following error:

So it appears I have a parsing error, but I am not sure where to look next for that. I know I'm missing something, but am not sure what. Any assistance that can be given to point me in the right direction would be appreciated. Thank you.

Hi there, I realize I'm about a year late to the party, but in case this is still an issue, or if someone else comes to this from googling the parsing error as i did i wanted to still comment.

The ES parser cannot handle white-space, so if there's any white-space in the file you'll get this error.

I opened my file in vim, after trying to escape all the things, quote the descriptions, etc, and what finally got it to import was running :%s/\ //gafter replacing my spaces in the description with underscores.
