ApiKey basesd rate limit for calls to /token #489

Open rodrigomaraujo opened 3 years ago

rodrigomaraujo commented 3 years ago

Hello guys, I´m using node-red-node-watson for a production service receiving input for a VoiceGateway and WhatsApp API. It´s not a so big service, but we reached 300 to 500 simultaneous users chating. We implement Watson Assistance calls with 'watson-conversation-v1´ node.

At peak times whe are getting "ApiKey basesd rate limit for calls to /token" error message. IBM Labs says that´s because we generate a Auth every message that sent to Watson Assistance service.

Anyone get this error too?

I am not very knowledgeable about the Watson APIs and NodeRed implementation, is it possible to reuse an instance of IamAuthenticator between multiple calls to the service?

The Assistant node could be reworked to cache an Authenticator until it expires.

I am open to pull requests with this change.
