We are using a self-hosted build agent which has the same NPM and node.js versions as the Microsoft hosted build agent installed:

NPM 10.8.2
Node 18.20.5

It looks like as if the task is installing and using deprecated packages. Please advise.

Start with the npm install command and pinned package versions shown in the issue, then trace where the task defines or invokes that installation. Check whether the deprecated dependencies come from the task's direct versions or their transitive dependencies; the work is done when the task no longer emits these warnings on the stated Node.js and npm versions.
