return endpoint restful http message instead of statusText

[al-oath]

in file
endpoints/restful/src/index.ts

in method request ... fetch
if not response.ok you throw error with the response.statusText
instead of the real http response object mesage

this is the change i'm suggesting:
if( response.ok ) { return response.json() } else { return response.json().then((data) => { throw new Error(data.message); }); }
