Create the timeout race only when timeout > 0.
backend-client.ts and attribute-filters.tsx call cancellableFetch without timeout. The helper still schedules setTimeout with undefined, which creates a zero-delay timer. That timer can win before the fetch completes. For non-POST requests, the rejection handler then converts the result to undefined instead of propagating the error. Guard timer creation and include the timeout promise in Promise.race only when requestTimeout > 0.

Rethrow the non-POST request failure.
This rejection handler logs the failure and then resolves with undefined. The surrounding catch does not run. For example, getLogs can dispatch an undefined response instead of setting logsError. Log the failure, then throw error.

Store pagination failures in moreLogsError.
The moreLogsError action sets logsError and clears moreLogsError. A pagination failure therefore replaces the main log state and the newly returned moreLogsError is always undefined. Preserve logsError and assign action.payload.error to moreLogsError.

Convert the timeout durations to milliseconds.
cancellableFetch and consoleFetchJSON use milliseconds. The non-tenant request uses 100 ms instead of 100 seconds. The pagination request uses 2 ms instead of 2 seconds.
