I wanted to know why I am still getting the same error: "TypeError: "ikm" must be at least one byte in length" . Even though I have used this link https://bcrypt-generator.com/ to store my password in the database.

please stop tagging here it is distracting. A quick google shows that this is a result of nextjs auth not seeing a top level secret defined. Have you set

NEXTAUTH_SECRET

in your

.env

file yet?

apologies for the inconvenience caused to you. yes I have set that in .env file
