Error missing parameter nonce

[f-w]

Suppose client runs on http://localhost:8000, OP sends following redirect

http://localhost:8000/oidc-callback#error=invalid_request&error_description=Missing+parameter:+nonce&state=9fc35a9169cd4763975503d6caf6c1bd

Tried https://github.com/perarnborg/vuex-oidc-example same error.
I know this could be caused by extra restrictions my OP imposes. But there is no option to either auto-generate nonce or supply one in config.

Sorry for this late reply.

Are you using the PKCE flow? I believe oidc-client does not set nonce for PKCE, only for implicit flow. But you should be able to set a nonce by sending it in the authenticate calls as an extraQueryParams option:

this.authenticateOidc({ options: { extraQueryParams: nonce }}

See the creator of oidc-client's reply in this issue:
