react is a framework, its not going to be setting headers, can you elaborate on what you mean by that?
all the headers we got are set automatically by the browser. none I've additionally set via axios library
im sorry but that isnt answering the questions ive asked
have you confirmed that CORS headers are being set locally?
I haven't manualy set any so far. But now I've set below and didn't change anything.
This also does not answer the question, im not sure where the confusion is coming from?
ill try to clarify further, have you confirmed that your go backend setting the cors headers when testing locally?
yes locally my go backend sets access-control-allow origin as localhost:3000 (my react app) successfully.
