JOLT spec on adding default values based on a condition - jolt

Question

If my input contains "WorkflowCategory" in "metadata", then output should contain workflow.workflowInputProperties with specified default values - having duplicate values (like "" string, 3 etc). If not, workflow.workflowInputProperties should not be added.
Input 1
{
"template": false,
"active": true,
"metadata": [
{
"value": "bank_",
"key": "AssetNamePrefix"
},
{
"value": "-BERG",
"key": "SuffixForPublicId"
},
{
"value": "false",
"key": "CORSEnabled"
},
{
"value": "Capture",
"key": "WorkflowCategory"
},
{
"value": "HD",
"key": "Features"
}
],
"description": "Template for working with PRI",
"name": "prof_name",
"type": "Live",
"id": "BNK056003413",
"version": 6
}
Input 2
{
"template": false,
"active": true,
"metadata": [
{
"value": "HD",
"key": "Features"
}
],
"description": "Live Template",
"name": "Live_HD",
"type": "Live",
"id": "BNK007596994",
"version": 1
}
For Input 1, output should be
{
"id" : "BNK056003413",
"name" : "prof_name",
"metadataSet" : {
"description" : "Template for working with PRI",
"type" : "Live"
},
"workflow" : {
"workflowInputProperties" : {
"assetNamePrefix" : "bank_",
"recordId" : "",
"sourceUri":"",
"processingUri": "",
"recorderType": "ABC",
"completionTimeout": 600
"loopBackTimer": 10,
"numberOfRetries": 3,
"numberOfRetriesForScheduling": 3,
"scheduleDelay" : 3600
},
}
}
For Input 2, output should be as follows, without workflow.workflowInputProperties
{
"id" : "BNK007596994",
"name" : "Live_HD",
"metadataSet" : {
"description" : "Live Template",
"type" : "Live"
}
"features" : "HD"
}

Answer 1

You should add below code to the rest of your spec. The only issue is that I cannot put empty string and I change it into space. I'll try to figure it out.
[
{
"operation": "shift",
"spec": {
"metadata": {
"*": {
"key": {
"WorkflowCategory": {
"#bank_": "workflow.workflowInputProperties.assetNamePrefix",
"# ": [
"workflow.workflowInputProperties.recordId",
"workflow.workflowInputProperties.sourceUri",
"workflow.workflowInputProperties.processingUri"
],
"#ABC": "workflow.workflowInputProperties.recorderType",
"#600": "workflow.workflowInputProperties.completionTimeout",
"#10": "workflow.workflowInputProperties.loopBackTimer",
"#3": ["workflow.workflowInputProperties.numberOfRetries",
"workflow.workflowInputProperties.numberOfRetriesForScheduling"],
"#3600": "workflow.workflowInputProperties.scheduleDelay"
}
}
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"workflow": {
"workflowInputProperties": {
"completionTimeout": "=toInteger",
"loopBackTimer": "=toInteger",
"numberOfRetries": "=toInteger",
"numberOfRetriesForScheduling": "=toInteger",
"scheduleDelay": "=toInteger"
}
}
}
}
]
