R taxize gnr_resolve function Internal Server Error (HTTP 500) for specific name

[abergelm]

I am using the taxize gnr_resolve function to resolves a long list of species names (about 8000 thousand). I am getting an error with the gnr_resolve function when it reaches "Mandevilla xamabilis". I'm not sure if this is a bug, but the function throws this error when trying to resolve this name.

gnr_resolve("Mandevilla xamabilis",
            best_match_only = TRUE,
            canonical = TRUE,
            http="post",
            preferred_data_sources=c(6, 11, 165))

Returns the error Error: Internal Server Error (HTTP 500)

It seems like it might have to do with the placement of the "x"? The function works fine for both "Mandevilla amabilis" and "Mandevilla x amabilis"
