I am using the SIWC v2/accounts endpoint and I am getting a CORS error when I try to access this endpoint. This is a new error that I was not getting previously.
Let me give you a history (btw - spoiler alert - this endpoint is not working for me at the moment.)
Originally I was restricting users to sign-in-to-coinbase using their USDC wallet, so when I returned the first account in the list of accounts the v2/accounts endpoint was returning, it was only returning USDC. On Sunday, December 10th, I tried accessing the v2/accounts endpoint and it was returning VeChain information instead. I fixed this problem by calling v2/accounts/USDC.
Yesterday (Thursday December 14th), I was suddenly getting a CORS error when I tried to work with the v2/accounts endpoint or the v2/accounts/usdc endpoint. This is really strange, as I never needed to do anything with CORS before AND the other endpoints I called were working properly. I know that other APIs may give this error if there is a server-side problem.
From other posts, it looks like other users have seen errors related to this endpoint such as intermittent 401s and the v2/accounts endpoint returning the v3/brokerage/accounts data. These issues seem to have started appearing this week. My error is slightly different as I am getting a CORS error. I have even tried running the v3/brokerage/accounts endpoint, I also get the CORS error.
I am listing the error below:
Access to XMLHttpRequest at ‘https://api.coinbase.com/v2/accounts/USDC’ from origin ‘http://localhost:3000’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
coinbase.js:104
(BTW, I tried adding this header, and it doesn’t help.)
If someone can fix this ASAP that would be great. (If my app was live and this happened, this could be a big issue. I was planning on launching in Jan but this may push out the timeline.)
This is a massive problem for anyone’s ability to work with the API as all subsequent calls regarding a specific crypto require the account_id which is returned by these endpoints.
