Information Needed to Troubleshoot Dataset Loading Issues in Arize

·Jan 28, 2026 12:08 AM·

Hello, if a client is having issues loading datasets into Arize, what information is needed to help them with this? I don't know if bad variables or a large system prompt would present issues. We're trying to use prompt playground and prompt hub to A/B test a model switch before EOL for one model. Thank you.

Can you please provide a step-by-step checklist or code example for dataset validation and troubleshooting? 🔒[private user]

Hi, 🔒[private user] working with Evan on this... our datasets use a lot of XML syntax (though used more as a markup language so it isn't always going to nor meant to validate as XML)... it seems like this is the issue as I've now been able to get some data in (though not import a full dataset) and the data I did get in was with sanitized and/or removed XML tagging.
