ZIS flow transform question - transform value to be Null

Posted Nov 01, 2023

Hello, I have a use case where the ZIS flow goes into a certain state and then needs to change an already initialized value. I am having a hard time finding documentation on how to change a value using a transform action. Is this possible?

"modifyValue": {
       "Type": "Action",
        "ActionName": "zis:common:transform:Jq",
        "Parameters": {
           "data.$": "$.data",
            "expr": ' < expression to modify value to an empty string or Null >'
           },
            "ResultPath": "$.ChangedData",
            "Next": "nextAction"
 },

 

Thanks

    Hi Craig! I'm thinking that you might be able to do this by using the `gsub` command, along with the appropriate regex. I haven't done much with ZIS myself, so I might be off on this, but something like this might do it for you (changes in bold):

    "modifyValue": {
           "Type": "Action",
            "ActionName": "zis:common:transform:Jq",
            "Parameters": {
               "data.$": "$.data",
                "expr": '.something | jq 'gsub("^(?!\s*$).+"; "")''
               },
                "ResultPath": "$.ChangedData",
                "Next": "nextAction"
     },

    With the combination of ZIS and regex, I can't say for sure that this will work, but let me know how this goes for you!
