Messaggi d'errore criptici

A volte JOSM visualizza messaggi di errore piuttosto criptici. Per esempio, JOSM potrebbe visualizzare

• Bad Request Error header: Placeholder node not found for reference -13 in way -12 (Kode=400)

Di solito, questi sono i messaggi di errore generati dal server OSM. Non vi è un dettaglio di possibili messaggi di errore generati dal server OSM e JOSM in generale non può sapere con quali messaggi di errore che ha a che fare.

JOSM farà del suo meglio per trasformare criptici messaggi di errore in un testo più comprensibile (inclusa la traduzione). Per favore segnalare al team di JOSM se appaiono dei messaggi criptici e/o non tradotti. Gli sviluppatori cercheranno di trasformarli in un messaggio più user-friendly.

Error and warning dialogs

Unknown host

When you download data from or upload data to the OSM server JOSM tries to establish a connection with the OSM server. If it can't resolve its host name, it displays the following error message:

How to resolve

• check the URL displayed in the dialog (in the example above it's http://nosuchhost.openstreetmap.org/api)
• make sure your preferences include a valid URL to the OSM server. The standard URL is http://api.openstreetmap.org/api.

Can't initialize OSM API

When you download data from or upload data to the OSM server JOSM tries to establish a connection with the OSM server configured in the preferences. If JOSM can connect but if it detects that there isn't a supported OSM server on the other end it displays the following error message:

How to resolve

• check the URL displayed in the dialog (in the example above it's http://api07.dev.openstreetmap.org/api)
• make sure your preferences include a valid URL to the OSM server. The standard URL is http://api.openstreetmap.org/api.

Network unavailable

When you download data from or upload data to the OSM server JOSM tries to establish a connection with the OSM server configured in the preferences. JOSM displays the following error messages if there's a problem with your Internet connection:

How to resolve

• make sure your computer is connected to the Internet. Can you open the URL ​http://www.openstreetmap.org in your preferred web browser?

Internal server error

When you download data from or upload data to the OSM server JOSM tries to establish a connection with the OSM server configured in the preferences. JOSM displays the following error messages if an error occurs on the remote OSM server:

How to resolve

• This is most likely a temporary problem. You're adviced to retry uploading or downloading after a short periode of time.

Imagery: Error loading Bing attributions

To use the Bing aerial pictures, JOSM has to download the Bing aerial attributions first.
This download can fail due to connection problems. JOSM shows you the message: Error loading Bing attributions, at the bottom right corner of the main window:

How to resolve

• Use a proxy-server. (Look for a http proxy list in the world-wild-net).
• Go to the preferences (F12) and set up JOSM to use a proxy under Connection Settings.
• If it does not work try a different proxy from the list.
• The attributions are only downloaded once. JOSM keeps them for the session. This means you should revert your preference to not use the proxy once Bing works.
