`generateJWT` method does not respect function changes

[danwbyrne]

Description

The endpoint we use for fetching a JWT for iterable is itself behind a jwt authorizer - when this user token expires it is unknown how to pass this change to the generateJWT function already initialized in iterable.

Code example:

import { initialize } from '@iterable/iterable-web-sdk'

const IterableProvider = () => {
    const enabled = useFeatureFlag('iterable')
    const { userToken } = useUserToken();
    
    const handler = useCallback(async (request) => fetchJWT(userToken, request), [userToken])
    
    const iterableFunctions = useMemo(() => {
        if (enabled) {
            initialize(apiKey, handler)
        }
    }, [enabled])
}

in this scenario when the userToken expires and a new iterable JWT needs to be requested the jwt request will fail because it continues to use the expired token. Other workarounds I've tried are using a ref for the function, calling initialize again when the update happens, but none of these will update the generateJWT method.

Possible solution would just be giving us access to some kind of setGenerateJWT functionality.

Apologies for the delay on this one. Will discuss with the team and get back to you. Have you been able to find any workarounds in the meantime?

@mprew97 our solution is to not use jwt api keys

Following up here, this should be handled OOTB by our SDK. If we receive a JWT failed error from the Iterable API, we will retry the generateJWT method that has been passed to us.
