No agent found in pool DartPool which satisfies the specified demands:
msbuild
DotNetFramework
vstest
node.js
Agent.Version -gtVersion 2.115.0

The only one of those "demands" that my build server might not meet is "node.js". If node.js is a dependency of this extension, then the installation instructions should include how to install it.

Installing node.js using the 64-bit Windows Installer (.msi) from https://nodejs.org/en/download/ and restarting Windows did fix that error.
