Comment:

 Replying to [comment:2 titodevera]:
 > The error only occurs when i retrieve all post meta data from a post,
 it's working well when I specify a meta_key as in your example (second
 get_post_meta() param)

 My apologies! I missed that.

 In that case, It's intentional, and it looks like the documentation needs
 updating. The function is a wrapper for
 [https://developer.wordpress.org/reference/functions/get_metadata/
 get_metadata()] which does correctly document it.

 If someone wants to whip up a patch to update the function docs here
 that'd be great :)
