As part of onboarding Microsoft Defender for Cloud-AWS, Was able to create CFN stack successfully in AWS but getting the following error after clicking on the Generate button while setting up Environment for AWS:
{"statusCode":409,"errorMessage":"error occured for security connector: Failed to create security connector, another security connector with same heirarchyId already exists for this native cloud account","errorCorrelation":"94ab46bf-6aed-45b8-9a88-feaba6949358"}
Not sure where to find this conflict/heirarchyId. Any help is much appreciated

I am having the same problem but with GCP, it occurred for me when I tried to add another connector because my first one is not working properly . Did you ever find a solution?
Hi @Dean Gross ,
Nope, still waiting for the response from MS team. We successfully created connector for the 1st time with Free trail subscription and later when the subscription expired we tried to create new connector, that is when we are seeing this issue.
If the Security Connector already exists then not sure where to find it to delete the old one and create new one. Error notification just gives the JSON data with some random hierarchy-id, other than that no useful information in the exception message.

Did you remove existing connectors created with the classic cloud connectors experience, as explained here:

Hello @Jeevan Reddy ,
I have discussed this with Azure Support. Looking the similar issues reported to support by other users, it has been said that the issue isn't with Microsoft Defender for Cloud.
Azure technical support will be able to check and guide further. I would recommend you to open an azure support case. If you don't have the ability to open a technical support ticket, please let me know I can help you further on this.
Much appreciated your response, unable to create azure support ticket. Can you please help us in creating ticket with Azure team.

I had similar issue, the reason was that on another subscription I had an agent connected to same AWS account. Deleting the previous agent allowed me to create new one.

Circling back, I am having this exact same issue in two different azure environments ---- was there ever a resolution? I am assuming at this point that its an MDC back end issue where metadata is not getting erased from the deleted aws account. If I have to Ill submit a ticket, but hoping not to. Thank you all in advance for any input and support!
