+(node:77996) [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file:///C:/Users/.../Documents/.../pivat/test.creative-crafter.de/tools/supermarket-finder/server.js is not specified and it doesn't parse as CommonJS.
+Reparsing as ES module because module syntax was detected. This incurs a performance overhead.
+To eliminate this warning, add "type": "module" to C:\Users\...\Documents\...\pivat\test.creative-crafter.de\tools\supermarket-finder\package.json.
+(Use `node --trace-warnings ...` to show where the warning was created)
