The request includes at least one invalid\/malformed connection photo id - google-streetview-publish

Question

I'm using Google StreetView Publish API to connect photos in a virtual tour and to some external photos on Google StreetView such as a road.
This is the API I use:
https://developers.google.com/streetview/publish/reference/rest/v1/photo/update
And this is the body of the request:
{
"pose": {
"heading": 26,
"latLngPair": {
"latitude": 47.707604844777,
"longitude": -124.41849471719
}
},
"places": [
{
"place_id": "ChIJvcvraDvfjVQR45a-VRk0lGs"
}
],
"connections": [
{
"target": {
"id": "CAoSLEFGMVFpcE5fWGtUZTFWV3dxRm9tOEFlRHVmYVdvTmdDR2NueVZ0dzhid0ZX"
}
},
{
"target": {
"id": "rQfq6hLfyFVfC0V43rrWDw"
}
}
],
"captureTime": {
"seconds": "1653027016"
}
}
But I'm getting this error message when I'm trying to add external panorama ID ({"target":{"id": "rQfq6hLfyFVfC0V43rrWDw"}} to the connections array.
{
"error": {
"code": 400,
"message": "The request includes at least one invalid\/malformed connection photo id.",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com\/google.rpc.ErrorInfo",
"metadata": {
"EXTERNAL_MESSAGE": "The request includes at least one invalid\/malformed connection photo id."
}
}
]
}
}
Does Google let to connect your panoramas to the Google StreetViews panoramas such as street photos, etc? Or what I was doing wrong? Thank you in advance

Answer 1

You can not link your panoramas directly to Google Street View panoramas.
For a while, Google connected the tours automatically, if they were in a certain range. They stopped doing this and undid those connections, so at the moment both exist side by side on the same map.
