@6543
I believe it's because you made a type definition, not a struct.

type CommentReactionList []*CommentReaction

I think what you want is

type CommentReacionList struct {
    CommentReactions []*CommentReaction `json:"comment_reactions"`
}

or something similar

Reflect is mad because a type definition reflection doesn't have a NumField

@jolheiser thanks this fixes the reflection ...

[6543]

because there were no "reactions" anymore ... I'll implement the API like described in #8313 (comment) ... hopefully this is good enouth

#9220 replace this PR
