Cannot read properties of undefined (reading 'toLowerCase')

[hi-its-lukas]

Hi,

does anyone know what this error message mean?

"Cannot read properties of undefined (reading 'toLowerCase')"

I am struggeling with setting up the connection to my Windows LDAP Server

Thx,
Lukas

Where do you encounter this issues? It sounds like some Javascript variable which is expected to be a string is actually undefined but really we need more context here.

during the sync process to fetch user and groups from my Windows AD

Here is a Log-File from the last sync i tried

So the crash happens at https://git.cloudron.io/cloudron/box/-/blob/master/src/externalldap.js?ref_type=heads#L49 we will provide a fix to have a better error message, but generally this will not "fix" the issue.

Looks like some LDAP object from your LDAP server is returning a user record without a username field.
Could this be the issue?

[nebulon]

The crash will at least be fixed with next Cloudron version https://git.cloudron.io/cloudron/box/-/commit/14a18a42b777771796b46c7714cc2ab23c0085d5

@nebulon so I solved the problem. The was an E-Mail missing in one of the user. After adding the E-Mail we sync was succesful

Glad it worked out in the end. With the next release we will have a better error handling to find those issues faster.
