Does anyone have Masa 7.4.2 running on Adobe Coldfusion 2021 in Command Box? We have a project currently on 2016 but when switching server to 2021 we get the following error:

500 Error
Element SETTINGSBUNDLEBEAN is undefined in a CFML structure referenced as part of an expression.
Type:Expression
coldfusion.runtime.UndefinedElementException: Element SETTINGSBUNDLEBEAN is undefined in a CFML structure referenced as part of an expression.

We do not use command box, but do have Masa working on 2021

That error usually means it can't parse your settings.ini.cfm file correctly. Did anything change in the file during the update .... or more importantly, file permissions or what user ACF us running as?
