iOS game crashes instead of showing an ad after Unity Ads package was updated to the latest version (3.7.1 as of writing)

Basically, it says in log output in Xcode:

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘*** +[NSString stringWithUTF8String:]: NULL cString’
terminating with uncaught exception of type NSException

I have no idea what to do here. Anyone had similar situation? I don’t know how to fix it. Everything works well with older Unity Ads version, it shows ads and all.

Hi @spilat12

I was facing exactly the same issue, this worked for me.

I suggest that you try the solution by this Angel right here ( @JindoBlu )

(SOLUTION)

" changed Advertisment.Show() to Advertisment.Show(“video”) "

or whatever the override you were using, just use the one with “AdPlacementID”
