問題

  • など、Swagger UIからPUTメソッドを実行した場合(これはUIから生成されるリクエストです):
url -X 'PUT' \
'http://localhost:8080/o/headless-delivery/v1.0/documents/183873/permissions' \
-H 'accept: application/json' \
-H 'Content-Type: */*' \
-H 'x-csrf-token: a5GuDT5U' \
-d '[
{
"actionIds": [
"UPDATE",
"VIEW"
],
"roleName": "Site Member"
}
]'

JSONが正しいのに、以下のような400レスポンスステータスが表示されます:

{
"status": "BAD_REQUEST",
"title": "Input is invalid JSON"
}

Environment

  • Liferay DXP 7.4
