it used to be simplistic... i like how overtime it has become more technical and theoretical information , the technology has become so high level and abstract.. that if u dont go to university... its really hard to learn from top to bottom... for me atleast... im currently implementing oauth2.0 SSO flow, and im sure im doing everything right, but have weird issue in Koa, using node-fetch , SSO resource owner , refuses, to send me aa json paiload back, like ... ;S says syntaxERror : Unexpected end of JSON input... im 100% sure that that fetch body payload is form urlencoded ;S im going crazy already, i ve asked few people, they all say i have written everything correctly, not a single AI model also thinks i have written something wrong.. ;s i even looked up some express examples of other people guides on implementi lets say oauth2 with google, i literally did it the same way as anyone else... does anyone know if node-fetch 3.3.2 is broken on windows platform or smt?... isnt unexpede end of json input like... if json is malformed? does windows and linux have different newline in http post request / response? im starting to think the sso service provider is ignoring oauth2 spec , im just getting either 500 , or a pending Promise ;s wanted to write it myself... i guess im going to just install some Grant lib/framework to do it... wasting too much time ; ] being stuck in such stupid problem... is discouraging... ;s
