Some customers are seeing generic JDBC resource type queries fail with an error referencing LZ4 compression. Connection tests still pass, so the error appears only when running a query or loading a resource schema. We have identified the cause and are working on a fix.

- identified · Aug 20, 2026, 06:16 PM UTC
This issue affects Retool version 4.0.0+ (stable and edge), specifically for 1) newly-created React apps, 2) new publishes of existing React apps, and 3) cold starts of sandboxes when editing existing React apps. Existing published apps that do not get published after August 19th are unaffected. Self-hosted customers can update to 4.43.0-edge to get an immediate fix. A patch to our stable release channel is coming soon.
