Convex-auth fails to signUp or signIn

[reanzi]

I have used Convex-Auth just fine the last two weeks; but suddenly it stopped working in my development environment; I kept getting

Hit error while running `auth:signIn`:

So I tried to start a new project following the Convex-Auth docs, but to my suprise, signUp failed so I didn't try signing in;

 <form
        className="flex flex-col gap-2"
        onSubmit={(e) => {
          e.preventDefault();
          const formData = new FormData(e.target as HTMLFormElement);
          formData.set("flow", flow);
          void signIn("password", formData)
            .catch((error) => {
              setError(error.message);  // Prints "Cannot read properties of null (reading 'redirect')"
            })
            .then(() => {
              router.push("/");
            });
        }}
      >

I even tried passing "redirectTo" property to the function but nothing changes;

Is there anything that changed or am I missing something?

• These are related dependency packages for the example from docs:

  "dependencies": {
    "@auth/core": "^0.37.0", // Tried to manually add this
    "@convex-dev/auth": "^0.0.81",
    "convex": "^1.27.0",
    "next": "15.2.3",
    "react": "^19.0.0",
    "react-dom": "^19.0.0"
  },

• And these are from my main project:

"dependencies": {
    "@auth/core": "^0.39.1",
    "@convex-dev/auth": "^0.0.81",
    "convex": "^1.23.0",
}

Any help I will appriciate because I'm grinding halt here

Has anyone find a solution for this? Is this an issue on the Convex side?
