Why is the required builds merge check still failing after a successful build?

[Shevangi]

I am attempting to configure a similar setup as mentioned in https://community.atlassian.com/forums/Bitbucket-questions/Why-is-the-required-builds-merge-check-still-failing-after-a/qaq-p/2230801.

However even after following the inputs given in the response. I am not able to add the parent field.

shesh@xxxxx:~$ curl -u shesh:$BIT_PASS   -X POST   -H "Content-Type: application/json"   -d '{

        "key": "TEST-BUILD-1",

        "state": "SUCCESSFUL",

        "url": "https://jenkins.example.com/job/test/1/",

        "description": "Temporary test build status",

        "parent": "TEST-BUILD-PARENT",

        "ref": "refs/heads/develop"

      }'   "https://{url}/rest/build-status/1.0/commits/c11ff6158b956b876fe49fea831ddee954854c56"

shesh@xxxxx:~$ curl -u shesh:$BIT_PASS   "https://{url}/rest/build-status/1.0/commits/c11ff6158b956b876fe49fea831ddee954854c56" | jq .

//Parent field goes missing.

With the new Bitbucket endpoint : 

shesh@DKB00000C3NJ114:~$ curl -u shesh:$BIT_PASS "https://{url}/rest/api/latest/projects/{repo}/repos/{slug}/commits/c11ff6158b956b876fe49fea831ddee954854c56/builds" | jq .

{
"errors": [
{
"message": "Please specify a non-blank key smaller than 255 characters",
"exceptionName": "com.atlassian.bitbucket.validation.ArgumentValidationException"
}
]
}

And I think this is the reason for my check not being passed even when the job is completed successfully.

What am I missing to allow the required builds merge check to pass?
