JSON Error on Login

[jdalrymple]

Summary

After a fresh install, I go to login and after about 20 seconds, i see this error pop up in the login screen:

Environment

Hosting service: GCP e2-small OS: Debian Bullseye

Config

I kept the defaults from here, however ive updated the NEXT_PUBLIC_WEBAPP_URL to be my own domain.

Additional Notes

After the first login, I am also greeted with the message: "You are admin but you do not have a password length of at least 15 characters or no 2FA yet Change Password to gain admin access", but this has been reported already https://github.com/calcom/cal.com/issues/9527, https://github.com/calcom/cal.com/issues/9690

I've also tried to set up 2FA but entering my password isnt accepted and occasionally It just closes the modal:

Updates!!

I do see this error in the browser console:

Error setting up two-factor authentication SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data two-factor-auth-5a03d5ad2d4dbd78.js:1:5962 handleSetup NextJS

update 2

It looks like the fetch call to '...api/auth/two-factor/totp/setup' is returning an internal server error, which then sends back the JSON error when the response.json() function is called.

update 3

Default config is outdated. The newer config file makes sure to specify the length of the encryption key:

# Application Key for symmetric encryption and decryption
# must be 32 bytes for AES256 encryption algorithm
# You can use: `openssl rand -base64 32` to generate one
CALENDSO_ENCRYPTION_KEY=

update 4

So even changing the key to a 32 byte key using the algo mentioned above, the error still persists:

update 5

Doing some local testing with the touched code, it looks like the base64 encoding of the string generated through openssl rand -base64 32 command, is failing when converting into a buffer which sets the encoding to latin1, resulting in a 44 length string, not 32. This is what causes the error.

update 6

Temporary solution would be to just create a 32 character long alphanumeric string.

Oh! lmk if i should post this in cal.com instead of the docker repo! I figured since im using the docker image id post it here, but I wasnt sure!
