Answer 1

Check your WEBSITE_NODE_VERSION in the app service. You can also run node --version from terminal prompt either from the portal or Kudu console. I'm thinking you're running a lower version which is causing your issue. I know of someone that was running into a similar issue and their version was 6.12.3. Setting their version to 18.12.1 resolved their issue.
