What is the code that produces this? How can I reproduce it?

[suryavirkapur]

Followed development intructions on README.md: clone repo, switch .env.development to .env.local, and then run the project.

Are you sure that you didn't create a user with the same email before? I can't reproduce this problem

[suryavirkapur]

Just tried singning up with a new email. Same issue.

[suryavirkapur]

packages/stack-shared/src/utils/jwt.tsx at Line 35:

  issuer: string,
  audience: string,
  payload: any,
  expirationTime?: string,
}) {
  const secret = getPerAudienceSecret({ audience: options.audience, secret: STACK_SERVER_SECRET });
  const kid = getKid({ secret });
  const privateJwk = await jose.importJWK(await getPrivateJwk(secret));
  return await new jose.SignJWT(options.payload)
    .setProtectedHeader({ alg: "ES256", kid })
    .setIssuer(options.issuer)
    .setIssuedAt()
    .setAudience(options.audience)
    .setExpirationTime(options.expirationTime || "5m")
    .sign(privateJwk);
}

Is returning an await on a promise.

export async function generateAccessToken(options: {
  projectId: string,
  useLegacyGlobalJWT: boolean,
  userId: string,
}) {
  waitUntil(logEvent([SystemEventTypes.UserActivity], { projectId: options.projectId, userId: options.userId }));

  if (options.useLegacyGlobalJWT) {
    return await legacySignGlobalJWT(
      jwtIssuer,
      { projectId: options.projectId, sub: options.userId },
      getEnvVariable("STACK_ACCESS_TOKEN_EXPIRATION_TIME", "10min")
    );
  } else {
    return await signJWT({
      issuer: jwtIssuer,
      audience: options.projectId,
      payload: { sub: options.userId },
      expirationTime: getEnvVariable("STACK_ACCESS_TOKEN_EXPIRATION_TIME", "10min"),
    });
  }
}

And here there is an await on an await ...

This is not a function on the hot path, but thought would let you know.
