"404 Asset not found" while fetching the asset balance

Hi FB team!

I’m building my crypto wallet using NCW SDK and Node.js demo backend set up for using the sandbox.

Everything went good, I was able to create wallets, generate keys, fetch supported assets and add them.

The …/summary endpoint on the backend was also working good. Until yesterday.

Now I’m getting 404 from there and examining the logs shows that there’s 404 Asset not found error while calling the URLs like https://sandbox-api.fireblocks.io/v1/ncw/wallets/68899106-9850-4dd4-8467-d42114c2b7f1/accounts/0/assets/BTC_TEST/balance by the JS SDK under the hood.

At the same time, POSTing to the https://sandbox-api.fireblocks.io/v1/ncw/wallets/68899106-9850-4dd4-8467-d42114c2b7f1/accounts/0/assets/BTC_TEST returns 200 and GETting from the https://sandbox-api.fireblocks.io/v1/ncw/wallets/68899106-9850-4dd4-8467-d42114c2b7f1/accounts/0/assets successfully returns me a list of added assets, and the BTC_TEST and others are effectively in this list.

My FB sandbox has expired some time ago and I was thinking that this could be the problem, but creating another one didn’t help.

fireblocks-sdk is also the latest one, 5.38.0.
