Cannot provide empty campaign value when modifying character.

[garrickb]

You can recreate this buy creating a character, and then attempting to modify the character passing a "null" value for the campaign.

Response from server: {"Campaign":["The value 'null' is not valid for Campaign."]}

I think that this may fix my other issue of not being able to remove the campaign from a user by sending "null" to the modify command. I'm just gonna go ahead and lump that in with this, but make sure that you test that.

There are two issues going on here. 1, the error itself likely comes from you using x-www-form-urlencoded - since there is no "null" value in that encoding, youre sending the string "null." I encountered this in Postman, and changing it to json with an actual null value does not throw the error.

However, it still is a problem, because I have no way to distinguish when you specifically send a null value (when you want to remove a character from a campaign) versus when you omit the value (when you are making a modification to something other than the campaign). We can either leave this as-is (once a character is in a campaign, it must always be in one, somewhere) or I can add a boolean field like "forceUpdateCampaignId" to know what "null" means.

If it will be easy for it to know what "null" is, I think that would be a better solution, even though it seems a little haphazard.

[jackhorton]

so, boolean field specifically to mark whether or not you are intentionally setting campaignId to null? I suppose i could also fix this by just having another route to handle this specific case, rather than lumping it in with the rest of the character modifications.

Update -- changing to JSON actually makes the process silently fail. Please hold for new solution.
