Translations:NPM module - izara-middleware/82/en

• If have trouble managing promises to be awaited before Lambda returns, could add a new middleware where we register promises and await them all in the after middleware before returning
• Promise middleware could be a global class like CorrelationIds, maybe store both the promise and some other info, eg a tag in-case the promise rejects so we can log it
• AWS has maximum 10 message attributes so will need to be careful about this, might need to combine correlation ids into a serialized object but might hit limit for length of one attribute?
