geocoder.osm error cod 403

[rsjane]

When using geocoder.osm('Berlin'), python returns an error.

Status code 403 from https://nominatim.openstreetmap.org/search: ERROR - 403 Client Error: Forbidden for url: https://nominatim.openstreetmap.org/search?q=Berlin&format=jsonv2&addressdetails=1&limit=1

Same here (only on Windows computer). On macOS everything's working as usual.

Add the following function in the class OsmQuery(MultipleResultsQuery) in osm.py
def _build_headers(self, provider_key, **kwargs): """Will be overridden according to the targetted web service""" return {"User-Agent": 'My User Agent 1.0'}
This should be work.

def _build_headers(self, provider_key, **kwargs):
    return {'User-Agent': 'DenisCarriere-geocoder/1.32.1'}

Definitely helps. Nominatim API policies must have changed since the package was last updated.

This is a missing user agent in the request.

This was still not working for me. I added
'email': 'my@mail.com', <with an actual email there
to both the OsmQueryDetail and OsmQuery classes inside osm.py, as part of the query dictionary.
I also included the changes made here, just in case that was also necessary.

Here's what a full class looks like w/ the additional change:

class OsmQuery(MultipleResultsQuery):
