Axios 1.7.7 request config timeout default 0 documentation async-retry 1.3.1 retries only when promise rejects

💡 Result:

In Axios 1.7.7, the request configuration property timeout specifies the number of milliseconds before a request times out, with a default value of 0, which signifies no timeout [1][2][3]. Regarding async-retry 1.3.1, the library is designed to retry when the provided function throws an error or returns a promise that rejects [4][5]. If the function resolves successfully, async-retry considers the operation complete and does not retry [4][5]. Therefore, retries only occur when the promise rejects or an error is thrown [4][5]. Note that if you need to abort retries manually within the function, you can invoke the bail function provided as the first argument to the retrier [4][5].

Citations:

Bound the Terra LCD request.

axios.get(url) uses Axios 1.7.7 with the default timeout: 0. A stalled request remains pending, so async-retry cannot start another attempt and terraMinted may not publish a supply update.

Set a per-attempt timeout.

In `@src/adapters/peggedAssets/ust1/index.ts` at line 19, Update the axios.get
call within the retry callback to include a finite per-attempt timeout, ensuring
stalled Terra LCD requests terminate so async-retry can retry and terraMinted
can publish updates.
