+### >= v20.15.0
+This service requires Node versions 22 or higher. Earlier Node releases are no longer supported because dependencies (e.g. `lru-cache@11`) rely on `node:diagnostics_channel.tracingChannel`, which is only available in Node 20.2+ and is fully supported on Node 22 LTS.

+
 NOTE: Node LTS (`long term support`) versions start with an even number, and odd number versions are subject to a 6 month testing period with active support before they are unsupported. It is recommended to use sidecar with a stable actively maintained version of node.js.
