error in route_graphhopper

[sckott]

With route_graphhopper getting this

route_graphhopper("New York", "Oaxaca", vehicle = "bike")
#> Error in (function (classes, fdef, mtable)  : 
#>   unable to find an inherited method for function ‘coordinates’ for signature ‘"NULL"’

And I do have my graphhopper PAT in my env vars, so I am guessing that's not the problem

Does graphhopper_pat() return your API key? If I have an invalid API key I get the same result, but a valid one works. I have added a check to return a more useful error message when the API key is invalid in #112 .

[sckott]

It does return my key , I guess I can check if the key is still valid

[richardellison]

You can try adding silent=FALSE to the route_graphhopper call and then running the request URL and see if that returns a valid result.

[sckott]

I'll try that

[sckott]

this is erroring b/c when message slot doesn't exist it fails

if (grepl("Wrong credentials", obj$message) == TRUE) {
    stop("Invalid API key")
  }

at these lines: https://github.com/ropensci/stplanr/blob/master/R/routes.R#L213-L215

tried again, with a new API key, which works, but the request fails due to those lines of code above

[richardellison]

I see that now. Should be fixed in #116.

[sckott]

works great, thanks
