Jolt how to do this transform? Concat and set in array - json

Question

I have an input like this
{
"employee": {
"id": "123456",
"firstName": "John",
"prefFirstName": "Doe",
"lastName": "John",
"prefLastName": "John",
"mgrFirstName": "Mitch",
"mgrPrefFirstName": "Mitch",
"mgrLastName": "McEvoy",
"mgrPrefLastName": "McEvoy",
"gmFirstName": "GMName",
"gmPrefFirstName": "GMName",
"gmLastName": "GMLastName",
"gmPrefLastName": "GMLastName",
"dirFirstName": "DirFirstName",
"dirPrefFirstName": "DirFirstName",
"dirLastName": "DirLastName",
"dirPrefLastName": "DirLastName",
}
}
Expected output should be like this, I can't figure out the fields in bold.
"managers" : [ {
"chnl" : "eml",
"nm": "Mitch McEvoy",
“mgrlbl”: “Direct Manager”
}, {
"chnl" : "eml",
"eml" : "",
"nm": "GMName GMLastName",
“mgrlbl”: “General Manager”
}, {
"chnl" : "eml",
"eml" : "",
"nm": "DirFirstName DirLastName",
“mgrlbl”: “Director”
} ],
"nhstdt" : "2020-11-23",
"nhmob" : "",
"nheml" : "empp#web.com",
"mgreml" : [ "testttt#web.com", "testttt#web.com" ],
"mgrchnl" : "email",
"chnl" : "mob",
"nhnm" : "Doe John",
"mgrnm" : "Mitch McEvoy"
I have a transform like this but can't figure out how to get the desired output:
[
{
"operation": "shift",
"spec": {
"employee": {
"prefFirstName": {
"*": {
"#1": "tmpFirstName",
"#(2,prefLastName)": "tmpLastName"
},
"": {
"#(2,firstName)": "tmpFirstName",
"#(2,lastName)": "tmpLastName"
}
},
"mgrPrefFirstName": {
"*": {
"#1": "tmpMgrFirstName",
"#(2,mgrPrefLastName)": "tmpMgrLastName"
},
"": {
"#(2,mgrFirstName)": "tmpMgrFirstName",
"#(2,mgrLastName)": "tmpMgrLastName"
}
},
"mgrName": "managers[0].nm",
"mgrBusEmail": "managers[0].eml",
"gmName": "managers[1].nm",
"gmBusEmail": "managers[1].eml",
"dirName": "managers[2].nm",
"dirBusEmail": "managers[2].eml",
"#eml": ["managers[0].chnl", "managers[1].chnl", "managers[2].chnl"]
}
}
},
{
"operation": "modify-default-beta",
"spec": {
"nhnm": "=concat(#(1,tmpFirstName),' ',#(1,tmpLastName))",
"mgrnm": "=concat(#(1,tmpMgrFirstName),' ',#(1,tmpMgrLastName))"
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"mode": ["=toInteger", 0]
}
}
]
But I am not able to figure out how do I concatenate mgrFirstName and mgrLastName, gmFirstName and gmLastName, dirFirstName and dirLastName and after concatenation I need to set this in the array managers[0], managers[1] and managers[2] respectively.
I am not able to figure how do I modify an array which is in my shift spec after I concat the stirngs.

You can do the concatenation first with a modify-default-beta spec, then set the desired fields in the array. This should get you started:
[
{
"operation": "modify-default-beta",
"spec": {
"employee": {
"mgrFullName": "=concat(#(1,mgrFirstName),' ',#(1,mgrLastName))",
"gmFullName": "=concat(#(1,gmFirstName),' ',#(1,gmLastName))",
"dirFullName": "=concat(#(1,dirFirstName),' ',#(1,dirLastName))"
}
}
},
{
"operation": "shift",
"spec": {
"employee": {
"mgrFullName": "managers[0].nm",
"mgrBusEmail": "managers[0].eml",
"gmFullName": "managers[1].nm",
"gmBusEmail": "managers[1].eml",
"dirFullName": "managers[2].nm",
"dirBusEmail": "managers[2].eml",
"#eml": ["managers[0].chnl", "managers[1].chnl", "managers[2].chnl"],
"#Direct Manager": "managers[0].mgrlbl",
"#General Manager": "managers[1].mgrlbl",
"#Director": "managers[2].mgrlbl"
}
}
}
]
