I'm using keycloak

i have enabled Token exchange feature for getting keycloak tokens using the external IdP (google, microsoft, linkedin) also i have added the token exchange policy to be exchanging with specific client on my realm

everything is working except for linkedin, i'm using first broker login for creating user if it is first time, google and microsoft are working as expected, linkedin is working only if the user exists and associated with its provider user id, but if first time gives error: unknown_error and the logs of keycloak gives this

Can someone give help please!
