Hi APIM Team,
When i was trying to invoke a custom endpoint which dynamically changes
with a header value using a send mediator in my custom sequence, i
experienced a behavior where the request will go first to the endpoint of
my custom sequence after that it will send a request to the endpoint
specified when creating the API (Production endpoint) . I am trying to
understand the reason for two requests being sent in this scenario? I would
be grateful if you could explain to me why this is happening.
When API is invoked which uses the custom in sequence following was seen on
the wire logs. I have also attached the complete wire logs received to the
mail.
DEBUG - wire << "GET
/t/backstage/webapps/customerservice-1.1.0/services/customers/customerservice/customerservice/customers/123
HTTP/1.1[\r][\n]"
DEBUG - wire << "GET
/t/backstage/webapps/customerservice-default-SNAPSHOT/services/customers/customerservice/customerservice/customers/123
HTTP/1.1[\r][\n]"
I have attached my custom sequences as well. Your help will be much
appreciated on this matter.
Thanks and Regards
Shenavi
