Simple JSON nesting issue

Hi All,

I would like some advice/better solution to my query!

I am preparing some data to send in a table via email, the data structure is as below 

[{ "statusCode": 202, "statusText": "Accepted", "payload_file_name": "s3:///bucket/api-payload/archive/api_payload_20241023_140821324_j1.json", "receivedDate": "2024-10-28T13:25:26.6271537Z", "processedDate": "2024-10-28T13:25:26.6271537Z", "rowsCount": 2, "transactionId": "{a0aa71d8-5c0a-4bdc-a39f-a42bf5143c3b}" }]

I am preparing the fields in a parent pipeline and feeding the data as a string to a child, a mapper creates this using data.field_name formatting and "data" is passed as the pipeline parameter.

When the child receives this, I am having some trouble getting the below tweaked code (from another post by koryknick) to map the fields from horizontal to vertical format (easier to read in a quick email notification)

$email_data.entries().slice(0).map(x=> { "Field": x[0], "Value" : x[1] }

This code works fine directly in line with the mapper snap creating the data.field_name data, but when passed to a child, it gives it a set of square braces [...], and the code no longer works as it did. I have tried many forms of grouping and mapping, and come up with what I think is a hacky solution, which something better could replace.

My solution is simply to replace the [ and ] characters to nothing (.replace('[','')) in the incoming string to the child pipeline. I'm convinced there is a better way to do this with the expression language, but can't figure it out!

Without the replacing of the square braces

I've attached a sample pipeline with the mapping and payload as a parameter.

Thanks in adance!
