Microsoft Graph API OneNote pages content BadRequest - microsoft-graph-api

Question

I am using OneNote /content endpoint to retrieve page content as described here: https://learn.microsoft.com/en-us/graph/api/page-get?view=graph-rest-1.0
However, calling GET on /me/onenote/pages/{id}/content[?includeIDs=true] returns me this:
{
"error": {
"code": "BadRequest",
"message": "Resource not found for the segment 'content['.",
"innerError": {
"request-id": "6b7e5549-32a5-4b6f-80ed-ecacp9v41699",
"date": "2020-03-31T00:05:27"
}
}
}
calling GET on /me/onenote/pages/{id}/content returns this:
{
"_readableState": {
"objectMode": false,
"highWaterMark": 16384,
"buffer": {
"head": null,

"_transformState": {

}
Neither returns the actual page content. Any idea?

The "includeIDs" is an optional query parameter. Remove the square brackets around it to get rid of the Bad Request error. So the request should be GET on /me/onenote/pages/{id}/content?includeIDs=true
