ZIS flow working with multiple variables in a transform action

Hey all,

I've build a flow to update the phone identities of a user if specific custom fields have been changed.

What I did so far is, that I get the previous custom field value (e.g. +49 030123), it is the value of the variable: $.input.user_event.previous and with that I call the identities endpoint and find out the identityID to make an update with the current value ($.input.user_event.current).

That works very well so far with these expression:

"expr": '.identities[] | select(.value == "+49 030123") | .id | tostring',

Now I would like to use not the hardcoded number, rather the variable itself -> $.input.user_event.previous and my code looks like this:

 

"find_phone": {
          "Type": "Action",
          "ActionName": "zis:common:transform:Jq",
          "Parameters": {
            "data.$": "$.identities",
            "expr": '.identities[] | select(.value == "{{$.input.user_event.previous}}") | .id | tostring',
          },
          "ResultPath": "$.identity",
          "Next": "Ok"
        },

 

But it doesn't work, it seems that the previous variable is blank. It works only with a hardcoded value. So it seems that it is not possible to access to the input variable because the expression is within the data parameter $.identity (which is the API output of all identities of an user).

I am totally confused because if I use just a message to log it, works. My code looks like this:

"Ok": {
"Type": "Succeed",
"Message": "Phone need to be change. ID: {{$.identity}} Value: {{$.input.user_event.previous}}"
}
 
Does the transform action need the input variable as a second parameter to access to it? How can I handle it?
 
Thanks in advance

    Hi Nawed! I haven't had a lot of time to play around with ZIS, however, I'm wondering if the issue has to do with the single quotes that you use in the "expr":key. Could you switch that to double quotes and then remove the trailing comma if it's the last parameter in that object and let me know if that resolves it?

    Hey Greg!

    I tried it in this way:
    "expr": ".identities[] | select(.value == {{$.input.user_event.previous}}) | .id | tostring"

     
    Result:
    Action Error: zis:common:transform:Jq ActionState(find_phone) Error: Encountered parsing error: error parsing jq output: unexpected token "{"

    And in this way:
    "expr": ".identities[] | select(.value == '{{$.input.user_event.previous}}') | .id | tostring"

    Result:
    ActionState(find_phone) Error: Encountered parsing error: error parsing jq output: unexpected token "'"
     
    Any other idea?
