Crash running cubedash-gen - unexpected "platform" data type

[omad]

Looks like Explorer expects a string instead of a list for the Product platform field.

The word "claimed" is not present in the source code according to a git grep for me, what version of Explorer is this?

[omad]

Whoops, sorry, always should include that. Updated to say it's 3.0.2 which is older.

[pjonsson]

I made 50+ type error fixes between 3.0.2 and 3.1.0 and the raised exception isn't present in the source code any longer, so my guess is that this issue was fixed in one of those fixes. Can you try 3.1.0 and see if the problem remains?
