error when force users to change password in zimbra 10

[izadi60]

Hi
I installed ZCS opensource 10 on Ubuntu 20.04
I faced a problem: I want to force users change their password in first login.I check "Must Change password " for all users but when the user logged in to server it shows':
Internal Server Error

The server has encountered an internal error.
Please try again later.

Error 500
Is that a bug? what should I do?
any idea?
Thanks

This error is happening when the user is trying to login or when the user is created with option must change password?

[izadi60]

when "must Change password" is enabled and user login.
if "must change password" uncheck every thing is ok and user can login without any problem

[izadi60]

any idea please?

[yogesh.dasi]

Trying to reproduce this issue on our end but it didn't happen yet. Error which is thrown for getPasswordMinLength() as acct null there are other calls too which are executed on the same account object and there it didn't show any error as such. We are looking into it further to understand the scenario.

In the mean time could you add the debug logger on the account showing the error and see if there is anything shows up for error in mailbox.log.
Also could please share complete exception that you see for acct null.

This looks like an issue with faulty build creation, can you share steps on how you created the build?
