Unable to retrieve likes and commenter names/ids using getPost()

[kumarhk]

Hi all,

Thank you to @pablobarbera for a great package! I'm hoping someone can help me with two issues I'm having with the getPost() function.

1. No matter how I specify the function, I can't get it to output the three dataframes (post, likes, and comments) as desired. The "likes" dataframe is never generated.
2. In the comments dataframe that is successfully generated, the values for the variables from_id and from_name are always NA.

Here is some example code:

> id <- as.character(posts[589,"id"])
> id 
[1] "458400667664362_714715445366215"
> 
> qtd <- 100
> qtd
[1] 100
> 
> # Attempt with default values
> temp <- getPost(id, token=fb_token, n=qtd)
> length(temp)
[1] 2
> # list contains only two items: post df and comments df
> 
> # Attempt with comments=T, likes=T, reactions=F specified
> temp2 <- getPost(id, token=fb_token, n=qtd, comments=T, likes=T, reactions=F)
> length(temp2)
[1] 2
> # list contains only two items: gives only post df and comments df
> 
> # Look inside the comments df
> temp$comments[1,1:3]
  from_id from_name                                             message
1      NA        NA I missed  it,any other workshop? In the near future
> # from_id and from_name are missing

Hi @kumarhk,

The same problem just happened to me. It's because of a Facebook constraint for tokens not linked to the page admin. For more info see this comment on another issue: https://github.com/pablobarbera/Rfacebook/issues/172#issuecomment-366279411
