Hi,

When I create a new block I get 4 errors in the browser console when i run the site:

GET http://localhost:xxxxx/EPiServer/cms/Stores/contenttype/?dojo.preventCache=1486477841528 500 (Internal Server Error)

GET http://localhost:xxxxx/EPiServer/cms/Stores/contenttype/65?dojo.preventCache=1486477849051 500 (Internal Server Error)

GET http://localhost:xxxxx/EPiServer/cms/Stores/contenttype/65?dojo.preventCache=1486477849869 500 (Internal Server Error)

The error pages for those errors looks like this:

What version of epi are you running? Could you have a look in admin and see if you are using site specific assets folder or not? There was a bug a few versions ago where this strange error could occur.

I seem to be running 9.12.2 and I can't seem to find any site specific assets folder. Hmm, I'm still stuck at this...

I had a similar error the other day and I had an empty string in [ImageUrl("")] ...Any chance you have it to?

No, I can have a completely empty block and still get this error.

Hi,

I had a look at our code and saw that you can end up in this situation if you have added the ImageUrlAttribute to your models but you pass in a null value. e.g.

[ImageUrl(null)]

public class StartPage : PageData {...}

I'm not sure that is exactly what happens in your case, but it might be worth investigating.

I have reported an issue to make our code a bit more fault tolerant. It should be visible: http://world.episerver.com/support/Bug-list/bug/CMS-6515 when our issue sync job has run
