Can I use a loop to construct the response body when composing the response for a request using raw JSON? Below is my attempt.

"arrayName": [
    "{{#each (jsonPath request.body '$.[0].arrayName') as |node|}}",
    {
    	"type": "{{node.type}}",
    	"value": "{{node.value}}"
    },
    "{{/each}}"
]

But this result is like that.

"arrayName": [
    "",
    {
        "type": "aaa",
        "value": "bbb"
    }
    "",
    {
        "type": "ccc",
        "value": "ddd"
    },
    ""
]

I don't think you will need the

"

around the

each

template part

Thanks for your suggestion. But if I remove the

"

, the Wiremock server(I used a standalone server) occurs error.

Do you have response templating enabled ?

Sure, is it correct?

"transformers": [
    "response-template"
]

Would you be able to copy your mapping file so I can take a look at the whole thing and test

Here is the entire JSON.

Ah, cool. So, the mapping file needs to be valid JSON which is why you are having to put the

"

round everything. I think the example I gave you is correct but you will have to use

body

instead of

jsonBody

which unfortunately means you will have to escape everything in the response body. The other option is to pull out the response body into a separate file and reference it via the

bodyFileName

element. You can find more about that here - https://wiremock.org/docs/response-templating/

Thank you so much. I will try again by referring document you mentioned.

Let me know how you get on

Amazing!!! It works fine!! I really appreciate your assistance.

No worries. Glad it helped
