Hi Everyone,
I'm getting an error for some reason when I load any of my categories on either catalog ui, or commerce manager.

In commerce manager when I load up the categories I get the error..

Exception Details: System.InvalidOperationException: Sequence contains no matching element

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

In catalog ui, I just get a white screen however, when I open up dev tools and go to console, I see that I'm getting a 500 error while loading up a backend include.
The url for that is... /EPiServer/cms/Stores/contentdata/1073743626_344232_CatalogContent?dojo.preventCache=1423276404599

Here is my stacktrace for this error message...

Worth noting is we've imported these categories not that long ago using the commerce manager tools. We imported many other things and they mostly work fine, no issues editing or anything. Also we are having this issue on our qa server, while our dev server followed the same process and we had no issues.

Start comparing the databases on dev and qa, something seem to be missing in your Meta class definitions.

in the commerce database look in these tables to start with:

dbo.MetaClass
dbo.MetaClassetaFieldRelation
dbo.MetaField

Which version of episerver commerce are you using?

Which Version are you working on? 

Have you done any recent deployment on other enviornment? Has any new property been added in Meta class and probably, Meta Class is not updated.

Can you compare the Category Meta Class in both enviornments? Any difference?

Consider Language factor also.
