“ExplorationRuntimeNotReady” Error When Exploring S3 Data Connection in Foundry

Ask the Community

Hello,

I’m encountering an issue when trying to explore an S3 Data Connection in Palantir Foundry. Here are the details:

  • Error Message:

    Failed to load files
Unknown error occurred: STATUS ExplorationRuntimeReadinessService:ExplorationRuntimeNotReady

Here’s what I’ve tried:

  • Verified S3 bucket and IAM policies are correct.
  • Confirmed network allowlisting and VPC endpoint configuration.
  • Waited several minutes and retried, but the error persists.

Context:
I’m in the Data Connection app, attempting to browse files in an S3 bucket. The error appears immediately when I try to load the file listing.

Questions:

  • What does the “ExplorationRuntimeNotReady” error mean in this context?
  • Are there any steps I can take to resolve this, or is this an internal Foundry infrastructure issue?

Any guidance or suggestions would be greatly appreciated!

Thanks in advance.
