copy_field + double replace_all + array of objects and asteriks copies too often

[TobiasNx]

Input:

{
    "Hello": "World/download"
}

Flux:

inputFile
| open-file
| as-records
| decode-json
| fix(transformationFile)
| encode-yaml
| print
;

Fix:

add_array("encoding[]")
if exists("Hello")
  copy_field("Hello","encoding[].$append.contentUrl")
  add_field("encoding[].$last.type", "MediaObject")
  if any_contain("Hello","o")
    add_field("encoding[].$append.type", "MediaObject")
    copy_field("Hello", "encoding[].$last.embedUrl")
    copy_field("Hello", "image")
  end
end

replace_all("encoding[].*.embedUrl","download","preview")
replace_all("image","download","thumbnail")

Output:

---
Hello: "World/download"
encoding:
- contentUrl: "World/download"
  type: "MediaObject"
  embedUrl: "World/preview"
- type: "MediaObject"
  embedUrl: "World/download"
image: "World/thumbnail"

Expected:

---
Hello: "World/download"
encoding:
- contentUrl: "World/download"
  type: "MediaObject"
- type: "MediaObject"
  embedUrl: "World/download"
image: "World/download"

If replace_all("image","download","thumbnail") is outcommented the mapping is working correctly

The reproduction is needlessly complicated. The minimal Fix seems to be:

add_array("encoding[]")
copy_field("Hello", "encoding[].$append.contentUrl")
copy_field("Hello", "encoding[].$append.embedUrl")
copy_field("Hello", "image")

replace_all("encoding[].*.embedUrl", "download", "preview")
