What does HRESULT 0x80280034 (TPM_E_BAD_TYPE) mean?

TPM_E_BAD_TYPE

TPM_E_BAD_TYPE: follow the state transition

For TPM_E_BAD_TYPE (0x80280034), the failed transition is: a TPM parameter or resource has the wrong TPM-defined type for this command.

Capture before retry

capture command, parameter index, resource/handle type, serialized structure, and the API layer that built it.

Prove the fix at the owning API

construct the command with the documented TPM type and verify serialization before resubmission. Keep unrelated inputs unchanged so a changed result has diagnostic value.
