How to reference a secret with its field name including unsupported characters?

Hey @sungx2,

Thanks for reaching out to us!

Let me know if specifying the private key by id works. In the case of SSH, the id of the private key is private_key, so your full reference would look like op://Private/Github/private_key. Please confirm that the id is the same in your case, by running op item get Github --vault Private --format json and making sure the private key ID is indeed private_key. If this is not the case, let me know and we can pick it from here.

Best,
Horia
