cannot set additional field in sign up body

 const { user: createdUser } = await auth.api.signUpEmail({
        body: {
          email: userData.email,
          password: userData.password,
          name: userData.firstName,
          lastName: userData.lastName,
        },
      });
 const { user: createdUser } = await auth.api.signUpEmail({
        body: {
          email: userData.email,
          password: userData.password,
          name: userData.firstName,
          lastName: userData.lastName,
        },
      });

You can see that the lastName type is never. auth.ts is added in the comments below. Version: 1.3.26
No description
Solution:
Oh seems like it is fixed in v1.3.31. I was stuck in v1.3.26 because typeof auth.$Infer.Session; <- this had stopped working. This is also fixed in the new version, so I can upgrade now...
