Rahul Kurup commented on ATLAS-4410:
------------------------------------
Hi,
I tried the firing the jsons you have posted here in the jira to their
respective APIs to attempt to replicate but I feel there is some information
missing as I am encountering this error:
{
"errorCode": "ATLAS-400-00-01A",
"errorMessage": "invalid parameters: found null entity"
}
Would it be possible for you to provide additional information like the entity
typedefs for each of the entities and any other json used that is not mentioned
in the above jira?
