500 error when loading Content Type Icons

[rajambalj]

All of a sudden my content type icon urls changed from Geta_Epi_ThumbnailIcon to Geta_Optimizely_ContentTypeIcons. Also it was throwing 500 error.

input is null. But I have all the required startup code with the ForegroundColor and BackgroundColor. It just stopped all of a sudden.

Stack trace is as follows.

@rajambalj Can you show me your startup code and also an example of the attribute you use on a content type that is failing?

I'm facing a similar issue. It occurred after we moved our DXP to use Opti ID.

[rajambalj]

@degborta Here it is.

Also we are using Azure AD to login to Optimizely.

Ok thanks! can you also provide me with the generated url to the image @rajambalj ? Should look something like this:
/Geta_Optimizely_ContentTypeIcons?BackgroundColor=02423F&ForegroundColor=ffffff&Width=120&Height=90&FontSize=40&Character=61595&CustomFontName=&EmbeddedFont=fa5%2fwebfonts%2ffa-brands-400.ttf&UseEmbeddedFont=True&Rotate=None

[rajambalj]

@degborta
Geta_Optimizely_ContentTypeIcons?BackgroundColor=%23bf1238&ForegroundColor=%23ffffff&Width=120&Height=90&FontSize=40&Character=62566&CustomFontName=&EmbeddedFont=fa5%2fwebfonts%2ffa-solid-900.ttf&UseEmbeddedFont=True&Rotate=None

I even tried with removing those %23 also. It lead me to that null reference exception I mentioned above. (tried opening in new page)

We are also facing a similar issue and the same happened to us when switching to use Opti ID for CMS logins, if I follow one of the image urls I get the following message:
