LDAP authentication broken on 3.5.3

[matheusfillipe]

Steps to reproduce the problem

After updating to 3.5.3 trying to authenticate redirects to a blank page.

1. Have LDAP setup on .env.production:

LDAP_ENABLED=true
LDAP_HOST=127.0.0.1
LDAP_PORT=636
LDAP_TLS_NO_VERIFY=true
LDAP_METHOD=simple_tls
LDAP_BASE=ou=[redacted]
LDAP_BIND_DN=[redacted]
LDAP_PASSWORD=[redacted]
LDAP_UID=cn
LDAP_MAIL=mail
LDAP_SEARCH_FILTER=(|(%{uid}=%{email})(%{mail}=%{email}))
LDAP_UID_CONVERSION_ENABLED=true

This was working on previous versions

2. Try to login normally with email or password
3. You will get a blank page:

<- POST https://social.alive528.com/auth/sign_in
-> 422 Unprocessable Entity

Expected behaviour

Should login normally as before

Actual behaviour

Now im unable to login

Specifications

I am using mastodon 3.5.3. I am not sure what version was working before but it was released about 1 year ago.

Here is are the mastodon logs:

I also have an issue with ldap and im running mastodon version 4.0.1. I had to set LDAP_ENABLED=false in .env.production in order to get the site back up. Is there any new about how to fix this issue?
