Could not get geocoding results with geocoder-convertor

[K1kc4]

Hello,

I am trying to get graphopper-maps to work with local graphhopper-map, geocode convertor and nominatim, but i am having a problem that i am unable to solve.

Config:

routingApi: 'https://graphoppertest.local.test/',
geocodingApi: 'http://192.168.1.10:8080/nominatim',

Geocoding-convertor is conneted to local nominatim server.

Curl to geocoding-convertor:
curl -X GET "http://192.168.1.10:8080/nominatim?q=Berlin&locale=en"

Nominatim log

"GET /search?q=Berlin&limit=5&format=json&email=ybo%40gmail.com&addressdetails=1&accept-language=en HTTP/1.1" 200 3335 "-" "graphhopper-geocoder-converter (graphhopper-geocoder-converter)

But graphhopper is allays throwing me an error:

Error:

Could not get geocoding results because: TypeError: NetworkError when attempting to fetch resource.
requestAsync@http://192.168.1.10:3000/bundle.83488de722b6bf099361.js:71298:19

Am i doing something wrong, or it is a bug ? Would appreciate any help.

Hi @K1kc4,
since GH maps is built around the GraphHopper APIs, it also depends on the /geocode endpoint of the GraphHopper Gecoding API. With your config, graphhopper-maps would try to fetch from

http://192.168.1.10:8080/nominatimgeocode?q=...

In the code it is descriped here:

graphhopper-maps/src/api/Api.ts

Lines 82 to 108 in e30c34a

	async geocode(query: string, provider: string): Promise<GeocodingResult> {
	if (!this.supportsGeocoding())
	return {
	hits: [],
	took: 0,
	}
	const url = this.getGeocodingURLWithKey('geocode')
	url.searchParams.append('q', query)
	url.searchParams.append('provider', provider)
	const langAndCountry = getTranslation().getLang().split('_')
	url.searchParams.append('locale', langAndCountry.length > 0 ? langAndCountry[0] : 'en')
	// routing makes not much sense between areas and it is unclear if the center is on a road
	url.searchParams.append('osm_tag', '!place:county')
	url.searchParams.append('osm_tag', '!boundary')
	url.searchParams.append('osm_tag', '!historic')
	const response = await fetch(url.toString(), {
	headers: { Accept: 'application/json' },
	})
	if (response.ok) {
	return (await response.json()) as GeocodingResult
	} else {
	throw new Error('Geocoding went wrong ' + response.status)
	}
	}

graphhopper-maps/src/api/Api.ts

Lines 188 to 192 in e30c34a

	private getGeocodingURLWithKey(endpoint: string) {
	const url = new URL(this.geocodingApi + endpoint)
	url.searchParams.append('key', this.apiKey)
	return url
	}

I hope that I helped you with this.
