有人能告诉我，为什么每当我尝试通过Pipeline执行一个简单的Fabric Notebook时，总会收到以下错误信息：

Notebook execution failed at Notebook service with http status code - '200', please check the Run logs on Notebook, additional details - 'Error name - Exception, Error value - Failed to create Livy session for executing notebook. Error: {"code":"BadRequest","subCode":0,"message":"Encountered internal error while calling TokenProvider to get obo token. The return code is BadRequest, and no error details was provided.","timeStamp":"2026-04-22T11:12:08.3714474Z","httpStatusCode":500,"hresult":-2146233088,"details":[{"code":"RootActivityId","message":"1aff178c-4c62-46d8-910f-de7716b0a8a9"},{"code":"ErrorSource","message":"Fabric/Core Platform AuthNZ and Metadata"}],"exceptionCategory":0} HTTP status code: 500.' :

这对我来说真的让人费解。

我的设置非常简单

解决方案

对我而言，在移除连接后就能工作。Fabric Notebook可以在没有Notebook连接的情况下运行。现在我不确定为什么托管身份Notebook连接会出现这个错误。
