Array vs Non Array

[manohar]

hi there, I have 2 json files. one has the array and the other one has non-array child-structure.

The parent is also array. At the parent level I get individual records but when it comes to Child, if its non-array, then it mashes up the childs for each of the parent. it works fine if the child is also array.

Please find below the 2 files. E1EDPT2 is the child thats causing issue.

I am also attaching my pipeline one for the array and the other for non-array one. both having same mapping.

Can anyone please check and let me know where I m doing wrong?

Any help is greatly appreciated.

Thanks

Hello @manohar,

If you look at the Mapper screenshot below, is the expression sl.ensureArray(jsonPath($, "$LINES[*].E1EDPT1.E1EDPT2")) accomplishing what you want? It turns “E1EDPT2” into an array if it isn’t already one, then either in the same line or in a follow up Mapper snap you would run the next bit of processing. Let us know if that helps.

@rsramkoski thanks for that.

but when I try that, I get it as below

and at the end I still get it as

my end structure should come as below

[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-07-29 20:08 :-  Line 10 change Item text"
        }
      },
      {
        "line-num": "00020",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-07-29 20:08 :-  Line 20 change Item text"
        }
      },
      {
        "line-num": "00030",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-07-29 20:08 :-  Line 30 change Item text"
        }
      }
    ]
  }
]

hope that helps.

Thanks

@manohar You’re welcome, happy to help! I made a mistake with my initial pipeline with the expression sl.ensureArray(jsonPath($, "$LINES[*].E1EDPT1.E1EDPT2")), which ended up replicating the “TDLINE” items to every “POSEX” and ultimate leading to the merged string you observed.

I updated my pipeline to use a JSON Splitter to break “LINES” up first before performing sl.ensureArray($E1EDPT1.E1EDPT2) - effectively doing the same thing we did before but with no replication of “TDLINE.” Here is a screenshot of the pipeline:

Here is the final output of the “Construct Orderlines” Mapper Snap:

Also, since we’re using sl.ensureArray($E1EDPT1.E1EDPT2) to make sure “E1EDPT2” is an array, I also cleaned up your Mapper expression to remove the ternary expression that used typeof to determine if it was an array or object. The updated expression looks like this:
$LINES.map(x => {"line-num": x.POSEX,"attachments":{'type':"AttachmentText",'intent':"Supplier",'text': Date.parse(Date.now()).toLocaleDateTimeString({"timeZone":"US/Eastern", "format":"yyyy-MM-dd HH:mm"}) + " :- " + x.E1EDPT1.E1EDPT2.map(y=>y.TDLINE).toString().replace(/\,/g,"").replaceAll("<br/>","\n").replaceAll('], [','\n').replaceAll('[','').replaceAll(']', '')}})

Please let us know if this fully addresses your question or if not, where does this fall short.

An Alternative way of doing it would be on Mapper you can split $LINES[*].E1EDPT1 and in the mapper

sl.ensureArray($E1EDPT2)
