BetterAuth with custom Nextjs basePath

Hi everyone!
I'm working on a project that's hosted on a subdomain of a website, so I had to set a custom

basePath

basePath

in my Next.js configuration.

Now I'm having trouble getting BetterAuth to work properly with this setup. I adjusted the

basePath

basePath

for the

authClient

authClient

, and the best result I got was a POST request being sent to:

http://localhost:3000/custom_path/api/auth/sign-up/email

http://localhost:3000/custom_path/api/auth/sign-up/email

However, in the console, I get the following error:

ERROR [Better Auth]: Error [Error: NOT_FOUND]
POST /api/auth/sign-up/email 404 in 209ms

ERROR [Better Auth]: Error [Error: NOT_FOUND]
POST /api/auth/sign-up/email 404 in 209ms

I’ve already updated the

BETTER_AUTH_URL

BETTER_AUTH_URL

http://localhost:3000/custom_path

http://localhost:3000/custom_path

, but then the POST request was sent to:

http://localhost:3000/custom_path/sign-up/email

http://localhost:3000/custom_path/sign-up/email

And in the console, it only showed

sign-up/email

sign-up/email

.

Now I’m passing the full path to the client, using:

baseURL: "http://localhost:3000/custom_path/api/auth"

baseURL: "http://localhost:3000/custom_path/api/auth"

This looks correct in the network tab and seems to be received correctly, but I’m still getting the same

NOT_FOUND

NOT_FOUND

error.

Any ideas on what I might be missing? Thanks in advance!
