Internal Server Error when attempting to initialize a confidential VM that received an invalid secret

[hoh]

Describe the bug

An error 500 with the message 'Internal Server Error' is displayed when I attempt to initialize a confidential VM with confidential-init-session, after this command has been used with an invalid secret.

To Reproduce

1. Initialize a valid CocoVM with an invalid secret using:

aleph instance confidential-start 79724e4cba21ac034b1877e83b612db05edaf82aa8a66ee044fd788bfca8d00d https://dchq.staging.aleph.sh

2. (Optional) Confirm that the VM does not boot correctly from its logs:

aleph instance logs 79724e4cba21ac034b1877e83b612db05edaf82aa8a66ee044fd788bfca8d00d https://dchq.staging.aleph.sh

3. Call the function again.

aleph instance confidential-start 79724e4cba21ac034b1877e83b612db05edaf82aa8a66ee044fd788bfca8d00d https://dchq.staging.aleph.sh

This raises:

ValueError: HTTP error during operation confidential/inject_secret: 500, message='Internal Server Error',
