REST API Service - several problems

[lucTalend]

Hey 

I've create Rest service using tRESTRequest component , here's my flow :

On the "callback" path , I'm getting access token to external API and save it to context  , because this token is valid for 8 hours , I want to refresh it before expire.

To do this I use tSleep component but ..

1. when I've made POST call to "email" path , it looks like it triggers tSleep and codes are running ...

Trying to check how works "Wrong call" in tRESTRequest  , I've set it and in response it should give me Document with 500 response it works , but :

2. It triggers "email" Path and throws an error because of not enough parameters (parameter (this path is sending email with data send via body in Post))

How to handle this ?

Thank you
