[Resolved] Save edited trasnaltion in ATE

Background of the issue:
I am trying to edit and save a translation in ATE.

Symptoms:
The translation is not saving as expected.

And network API runs in the loop ...

{
"endpoint": "hidden link",
"params": {
"ui_language_code": "en",
"shared_key": "8b020c6c1634ceeb58f1eded80341929",
"uuid": "9fc3310a-5e85-4ae6-829d-6f52f31fa90d"
}
}

{
"endpoint": "hidden link",
"params": {
"ui_language_code": "en",
"shared_key": "8b020c6c1634ceeb58f1eded80341929",
"uuid": "d6463e4d-f189-4281-a8d0-7f0ff16044ae"
}
}

{endpoint: '

Questions:
Why can't I save the edited translation in ATE?
Is there a specific error preventing the save operation?
