i'm using Confluence Rest Api to create a new page :
That's my input
"{\"id\":null,
\"type\":\"page\",
\"title\":\" my new page\",
\"space\":{\"key\":\"TST\"},
\"status\":\"current\",
\"container\":{\"Id\":null,\"Type\":null},
\"ancestors\":[{\"Id\":2150269501}],
\"body\":{\"view\":null,\"export_view\":null,\"styled_view\":null,\"storage\":{\"value\":\" This page was created automatically \",
\"representation\":\"storage\"},\"editor\":null,\"editor2\":null,\"wiki\":null,\"anonymous_export_view\":null,\"plain\":null,\"atlas_doc_format\":null,\"raw\":null}}"
ancestor is the id of an existing page.
the new page is created, but on top level, not as child of my ancestor page.
What is wrong ?
