Hey,
I had issue with ts-node missing and then following error:
Invalid options object. Dev Server has been initialized using an options object that does not match the API schema. - options.allowedHosts[0] should be a non-empty string
it was simply adding following code to package.json to make the issue fixed:
"options": {
"allowedHosts": [ "localhost", ".localhost" ],
"proxy": "your localhost:port address"
}
I could not add link to proxy as a new user
