Rule Base Segment supported SDKs timeout (FME Only)

What to do

• Check whether your product depends on Harness. Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.

• Confirm your retries, queues and scheduled jobs caught up after the 0m it lasted.

  Anything that failed between 2026-04-28 21:48 UTC and 2026-04-28 18:27 UTC may need a replay.

• Subscribe to Harness's feed to hear about the next one first. RSS feed

   Requests made by SDKs with Rule Based Segments support could have gotten a null instead of an empty for responses with no Rule Based Segments, leading to an null pointer exception. Impact observed: 18:27 until 19:05 UTC. The impact for SDKs would have been a failure to initialize or process an update. Any change made to feature flags or RBS in an affected environment would re-generate any specific caches remaining.
