JQ: Delete key:value pairs anywhere in JSON tree - json

Question

I am looking for a way to delete key:value pairs (where key is a known string) anywhere in the JSON tree with jq.
Specifically: I would like to delete "type": "Link" and "linkType": "Entry" everywhere (in all parts of the hierarchy, where ever they appear). My JSON file is +800000 rows long and is nested deeply.
Snippet:
{
"entries": [
{
"sys": {
"id": "vcLKKhJ3mZNfGMvVZZi07",
"contentType": {
"sys": {
"id": "page"
}
}
},
"fields": {
"title": {
"de-DE": "Startseite",
"en-US": "Home"
},
"description": {
"en-US": "foo"
},
"keywords": {
"en-US": "bar"
},
"stageModules": {
"en-US": [
{
"sys": {
"type": "Link",
"linkType": "Entry",
"id": "11AfBBuNK8bx3EygAS3WTY"
}
}
]
}
}
}
]
}
I've tried so many different things to iterate through the file to remove these two from the output, I constantly end up with "Cannot index array with string". E.g.
[ .[] | select(.linkType != "Entry", .type != "Link" ) ]
Ideal result:
{
"entries": [
{
"sys": {
"id": "vcLKKhJ3mZNfGMvVZZi07",
"contentType": {
"sys": {
"id": "page"
}
}
},
"fields": {
"title": {
"de-DE": "Startseite",
"en-US": "Home"
},
"description": {
"en-US": "foo"
},
"keywords": {
"en-US": "bar"
},
"stageModules": {
"en-US": [
{
"sys": {
"id": "11AfBBuNK8bx3EygAS3WTY"
}
}
]
}
}
}
]
}
Can someone help me out?
Thank you for your help.

From the jq manual:
The walk(f) function applies f recursively to every component of the
input entity.
Use this to recursively go through all items, check your conditions and use del if necessary:
walk(
if type == "object" and .type == "Link" then del(.type) else . end
)
Edit: If "matching is less important", as you state, then just use del on any object:
walk(if type == "object" then del(.type, .linkType) else . end)
