Start with lib/node_modules/@stdlib/symbol/to-primitive/test/test.js at line 50 and inspect the Symbol.toPrimitive usage against the configured Node.js support range. Run the JavaScript lint target from tools/make/lib/lint/javascript/Makefile, and consider the issue done when the reported file passes lint and the workflow no longer reports errors.
