I am unable to transform json request body. I am on v3.2.1
The app definition is below.
I don’t think it matters but I am using .NET 5 api. There is no change in the request body using both file or base64 string. I also created templates in a template folder adjacent to apps as well as in root. The app is being loaded and I can tell the routing is correct (modified to wrong route and it won’t hit the endpoint).

(Additionally, I tried to transform xml request to json with transformation that creates json. But this is being ignored and xml is being sent to the api resulting in Http 415 Unsupported. Please note that this isn’t the main issue)
This is the request body.
{
"value1": "value-1",
"value2": "value-2",
"value_list": [
"one",
"two",
"four",
"three"
]
}
And this is the template.
{
"value1": "{{.value2}}",
"value2": "{{.value1}}",
"transformed_list": [
{{range $index, $element := .value_list}}
{{if $index}}
, "{{$element}}"
{{else}}
"{{$element}}"
{{end}}
{{end}}
]
}
Also tried with two others versions of tykio/tyk-gateway (v4.0rc21 and v3.0.4). Same result. There is no transformation.
Additional headers:
Content-Type: application/json
Authorization: default9f1f66b1404c4e95b8d44cf35b7d9074
That token is created with POST call to Create Tyk Token which sends body as below.

"per": 5,
"org_id": "default",
"access_rights": {
