What went wrong

When trying to find references of an argument to a function in a Go file using the Bingo (https://github.com/saibing/bingo) LSP, ALE throws an error which is shown below.

Error detected while processing function <SNR>141_NeoVimCallback[4]..ale#util#JoinNeovimOutput[2]..<lambda>10738[1]..ale#lsp#HandleMessage[30]..ale#references#HandleLSPResponse:                                                              
line    9:                                                                                                                                                                                                                                     
E714: List required

Reproducing the bug

1. Install ALE & Bingo
2. Open a .go file which has a function with an argument
3. Run :ALEFindReferences on the function argument:
   e.g.

           Here
            v
func test(hello string) {}

[w0rp]

Now ALE will handle null reference responses like this one.
