Hi @Serhan Genç
According to the error message, the Error AADSTS70001 is related to Microsoft Entra ID which is used for identity management using SAML-based SSO.
Reference: Error AADSTS70001 - Application with Identifier was not found in the directory
I suggest you post a new thread with Microsoft Entra ID tag in Q&A forum.
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.
Thank you for your understanding.********************************************
