Running into CORS error

[Anand-Issac]

from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I was wondering how to fix this error for the Search by keyword API

@Anand-Issac Kindly provide me more context how are you trying to access the library. Are you using in server-side or client-side using AJAX calls ?.

If server side, are u using express js ?.

I was using an AJAX call, the fetch API in react to use the ebay Finding API. I set a proxy in my package.json to solve the CORS issue but now I face a problem that after I deploy the application using Firebase Hosting, the API call returns an index.html response instead of the JSON response I got in my localhost server. I was wondering why this was so and if there is any solution to this ?

@Anand-Issac Ohh that's weird. Is there any URL or github link, I can check ?.

[Anand-Issac]

@pajaydev Yes sure: https://github.com/Anand-Issac/shopping-cart

[pajaydev]

Cool. I will take a look

[Anand-Issac]

@pajaydev Hey man. Did you figure out the problem yet?

[pajaydev]

@Anand-Issac Sorry was stuck in some other things, will look it up tonight

[pajaydev]

@Anand-Issac I can see its working fine in local (both read and write data from firebase).
if I am not wrong, you are facing issue after deploying. Kindly share me the URL where you have deployed the code.

@pajaydev Thanks for the help bro

If you try to request ebay API now on deployed app it will return a HTML file (my index.html) instead of the proper JSON response. It still says Status 200 though ... I'm not exactly sure why this happens

[pajaydev]

@Anand-Issac sure I will take a look. Thanks

@Anand-Issac I made a simple proxy using express JS to call this library.

Kindly take a look at it.

I would do like this to set up a simple proxy. Let me know if you face any issue.
Hope it helps.

[Anand-Issac]

Let me give it a try
