set ZERO_AUTH_JWKS_URL https://your-site.com/api/auth/jwks and in the token you can fetch for the jwt token from "/token" endpoint

That gives me the error "kind":"AuthInvalidated" │,"message":"Failed to decode auth token: JWTClaimValidationFailed: unexpected "sub" claim value"

bekacru•2w ago

can you guys try this version pnpm i https://pkg.pr.new/better-auth/better-auth@2194 and report back

Ok it worked with me, zero can can decode my jwt token through ZERO_AUTH_JWKS_URL='http://localhost:3000/api/auth/jwks' what i did was I removed the ZERO_AUTH_SECERT= and also i ended the cache server dev:cache rebuilt it with npm rebuild and it worked. i have no clue what made it work but yeah whenever i was runing into issues i just closed my cache dev and rebuilt and reran it

bekacru•2w ago

it worked with the version I sent above?

kenpachi•2w ago

no but i am on the latest version of better-auth I think the there is a conflict between the better auth secert and zero auth secert because whenever i add it i get the same error message

How are you getting the jwt from authClient.token without passing the header options such as cookie ? are you sure you are getting a jwt token?

const token = await authClient.token({
    header: {
        Cookie: `better-auth.session_token=${getCookie("better-auth.session_token")}`,
    }
})

const token = await authClient.token({
    header: {
        Cookie: `better-auth.session_token=${getCookie("better-auth.session_token")}`,
    }
})

authClient gets the cookies and headers automaticly so I don't need to spacify manually. also I've tried to get the token manually with authclient.token and It gave me a correct token
