Error: Getting Identity by DID, No Rows in Result Set

Question

What steps should I take if an error message says there's no identity found for a given DID?

Answer

This error occurs when a DID already exists in the vault but the database is cleared (e.g., running make down) without removing the DID from the vault. To resolve this, you need to delete the DID from the vault using make delete-did or make clean-vault and then run make generate-issuer-did again. After generating a new DID, start the container issuer-api-ui-1.

Wrong answer:

Trying to use the same DID without ensuring it's properly generated and stored in both the vault and the database can lead to persistent errors and failed verifications.
