encoding of identity failed

Error message

encoding of identity failed

What it means

identity.Serialize: PEM-encoding the identity's raw certificate (pem.EncodeToMemory) failed, so the serialized identity byte form cannot be produced. A guard over the local cert-to-PEM conversion; failure is unexpected for a parsed certificate.

Solutions

1. Inspect the wrapped encoding error for the exact cause
2. Verify the identity was constructed from a valid parsed certificate
3. Reconstruct the identity from the original certificate material
