Consumer API should respond with 400, not 500 when URL lacks of required parameters

[wajda]

Hi team,

Thank you for your support, I am new to Spline Agent and I request your help with the following issue:

I have integrated spline agent in a spark job and I can see lineage as well on Spline UI, I am trying to get Lineage json responses using Consumer API. I can successfully get API response for /data-sources, /execution-events endpoints but I am getting error when I am trying to hit curl -v 'http://localhost:8080/consumer/lineage-detailed/'
curl -v 'http://localhost:8080/consumer/lineage-overview/'
curl -v 'http://localhost:8080/consumer/attribute-lineage-and-impact/'
I am getting response as

*   Trying [::1]:8080...
* Connected to localhost (::1) port 8080
> GET /consumer/attribute-lineage-and-impact HTTP/1.1
> Host: localhost:8080

{"errorId":"7e718411-60a4-40ba-8eb4-c4016effb268","timestamp":1719309069776,"message":null}%

I have already checked the connectivity for Spline UI, Producer API and Consumer API. Kindly help me with the same.

Best Regards,
Mohini
