Valid values for ContentType

Question

I am creating a KAV article using Apex code. One of fields is a file field, and I set the various fields within there: Name, Content Type, and Body. It appears that I have to set the Content Type when doing this from Apex (unlike from doing it from the UI), if I try not to set it I get this error:

FIELD_INTEGRITY_EXCEPTION, Name, ContentType are required if Body is specified

Now the issue is that when I try and set the Content Type, some values throw errors. For example, if I try and set Content Type to "text/javascript", I get the error:

bad value for restricted picklist field: text/javascript

So my question is, are the valid picklist values for Content Type documented anywhere?

Answer 1

I was able to get the values using Describe methods, as discussed in this post:

how to get a picklist all values in apex controller

From this, I was able to figure out the list, which I will paste here if anyone else is interested.
