🧿 Current issues / What's wrong ?

On http error, (504, 524, etc...) where the getScore, getVp and validate fetch requests are unable to connect to api, the request is failing with a plain invalid json response body at https://... error

This does not have any indications on the caller side why the error is failing, and making it difficult to handle (should retry?)

💊 Fixes / Solution

API already return a well formatted JSON-RPC error, only cases where this json parsing error happens is for HTML response returned by cloudflare

We should return a meaningful JSON-RPC error when the HTTP request to the API is failing.

Example, on a timeout http error from cloudflare, the request will now rejects with

{
      code: 524,
      message: 'Gateway timeout',
      data: ''
    }

instead of rejects with a invalid json response body ... error, which is the last "unhandled" error om these endpoint.

🚧 Changes

• Try/Catch the res.json() call, to return a JSON-RPC formatted error, with the HTTP status and message
