TypeError: Cannot read properties of undefined (reading 'length')

[ahoh]

I successfully installed nodebb a week ago and it has been working well. However, I just found an error while looking at the log file.
This seems to be a database related error. The database I use is mongodb.
The following is the output:

Please post ./nodebb plugins, also try with no custom plugins.

Try disabling this and see if the issue goes away.

I can't see the source for that plugin. https://github.com/Annihil/nodebb-plugin-email-blacklist

@baris

This function is being called with an undefined requestedFields property. This shouldn't happen unless a plugin is doing something wrong. Check if any of your plugins are using the hook filter:user.whitelistFields you can take a look at /admin/advanced/hooks/

@baris it is here:

Actually, previously I wrote it here:

@crazycells said in Registration email domain blacklisting:

hi @julian , will this plugin be updated to work with NodeBB 1.19.0 ?

https://github.com/NodeBB-Community/nodebb-plugin-email-blacklist

currently, it does not prevent registration addresses from the blacklisted domains...

Additionally, the original repository is gone but the broken link is in the package.json, I guess it makes sense to update that too. Thanks in advance.

Maybe @julian can update the link...

I also did not make it work with 1.19.1, it would be great if it can be fixed. It is a very useful plugin.
