Advanced Configuration Editor on v19.6 — "Object reference not set to an instance of an object."

Simon (Annet) 6 months ago updated by Eric Davis (SDT) 3 months ago 10

I updated my cloud instance to 19.6.26188.7290.

On the Configuration page, when I click on any of the four links under 'Web Configuration', I get the following error message: "Object reference not set to an instance of an object."

This isn't the case with the links under 'Application Configuration' or 'Disable Host Client Menu Items'. They're working just fine.

ConnectWise Control Version:
19.6

I fixed your instance. Not sure how this happened, but I've seen it a couple times before. Somehow, one (or more) of the web.config keys gets saved without a "value" attribute.

Were the four web.config menus working properly before you upgraded?

Thanks Eric! Yes, that’s right — they were working fine before the upgrade.

It's happened again...

Fixed. Do you know if this correlates to some kind of change you make to your instance? (An upgrade, a specific configuration setting, etc.)

I'm having the same issue. A big issue because this plugin is how configure Duo MFA: https://docs.connectwise.com/ConnectWise_Control_Documentation/Get_started/Administration_page/Security_page/Enable_two-factor_authentication_for_host_accounts/Configure_two-factor_authentication_with_Duo

Of course, I only need DUO configured in ScreenConnect because of this other year long bug that prevents me from using SAML for several users (Our SAML handles DUO MFA): https://control.product.connectwise.com/communities/6/topics/2228-saml-fails-due-to-too-many-groups

What can I do to get this working?

EDIT: I edited the web.config file and found 3 keys missing the value entry. I've added value and now the plugin works.

+1

Still not sure how this is happening, but the extension will handle it in the next version. (And the SAML fix is slated for 20.3.)

Having the same issue with 19.6. Don't see any web.config keys missing value attribute. There are some keys with value=""

What needs to be changed to fix? Thanks

Do you know if any changes were made recently that might be correlated with this? I put a fix in the next version of the extension, but I'm still curious as to how this happens in the first place.

If you don't mind, I'd like to take a look at your web.config file: edavis@connectwise.com
