error in query

I want to get audio recordings from xeno-canto but at the moment both suwo and warbler give the same error for these functions

 `query_xenocanto` and    `querxc` 
```
Error in names(results)[match(c("id", "gen", "sp", "ssp", "en", "rec",  : 
  NAs are not allowed in subscripted assignments
```
