How to loop over nested JSON arrays, get values and then modify them based off index in shell using JQ - json

Question

this is the JSON I am working with -
{
"content": {
"macOS": {
"releases": [
{
"version": "3.21",
"updateItems": [
{
"id": 1,
"title": "Automatic detection for inactivity is here",
"message": "We've finally added a feature long requested - Orby now detects when you've been inactive on your computer. You can modify the maximum allowable inactive time through settings, or just turn it off if you don't need it",
"image": "https://static.image.png"
},
{
"id": 2,
"title": "In case you missed it... We have an iOS app 📱 🙌",
"message": "It's far from perfect, but it's come a long way since we first pushed out version 1.0. We don't that many users on it so far, but I'm hoping that it's useful. Please send any feedback and feature requests my way",
"image": "https://static.image.png"
}
]
}
]
},
"iOS": {
"releases": [
{
"version": "1.31",
"updateItems": [
{
"image": "https://static.image.png",
"id": 1,
"link": "orbit://com.orbit:/settings",
"message": "Strict mode offers a fantastic new way to keep your focus and get more done. To enable it, go to settings and toggle it on. Now when you want to run a timer, put your device face down on a surface. The timer will stop if you pick it up.",
"title": "Strict mode is here 🙌 ⚠️ ⚠️ ⚠️"
}
]
}
]
}
}
}
I want to translate all the title values and message values (I use shell translate).
In my attempt, I have looped through the releases, gotten the indices, then looped through the updateItems and gotten their indices, then translated the title and message based off both these indices, and then I've attempted to assign these new values to replace the existing title and message.
I've noticed that this results in all the title values being the same, and all the message values being the same.
I'm clearly using jq the wrong way, but am unsure how to correct.
Please help.
