Error fetching garmin mapshare link #2

Closed LW-Ho closed 6 months ago

LW-Ho commented 7 months ago

Hi, I configured my link, but there is an error with the setup.

This is debug message:

It looks like it's getting an empty response when it tries to download the feed.

You can try downloading the feed yourself by visiting (using your browser, or curl):

# (Replace NAME and PASSPHRASE below)
https://:PASSPHRASE@explore.garmin.com/Feed/Share/NAME

If that succeeds in downloading a KML file, then the name/passphrase should have worked in Home Assistant too. Consider sharing the contents of that file here (after editing out any private info) if it's still not working.

If not, please confirm that you are able to visit https://share.garmin.com/share/NAME in a browser (the normal way) using the same name and passphrase you provided during setup.

LW-Ho commented 7 months ago

Yes, my mapshare without password set, so replacing 'NAME' allows to download feed.kml.

So, I visited this link https://share.garmin.com/share/NAME , and my mapshare appeared as expected.

Thanks.

feed.kml.zip

BHSPitMonkey commented 7 months ago

The feed seems fine, and is parsed correctly when I load it into the integration code manually. I'm not sure why, but it seems like the fetch came back empty (which Garmin will typically do if the NAME is wrong or does not exist).

I've just pushed a new version (v0.2.4) with slightly better logging which may help with identifying the problem.

Hi,

this is debug messages, thanks your debug.

Received empty response from https://explore.garmin.com/Feed/Share/mushroomXXXXXXXXXXX

Does the logged URL here exactly match the URL you used earlier to download the KML feed?

doggkruse commented 7 months ago

I got bit by using my full URL where it really just wants the NAME component of the url in the setup

Yes, I can use this to download feed.kml

BHSPitMonkey commented 7 months ago

In that case I'm out of ideas for now 😕 Perhaps it's a temporary issue with Garmin's server and the updates will catch up eventually, or if you're using an outbound http proxy behind Home Assistant maybe there could be an issue there. The same request should have the same response in both cases.

Thank you for your response. I also use Sonoff and August components in Home Assistant and haven't encountered any network issues.

Thanks to the author!

BHSPitMonkey commented 6 months ago

I wonder if the issue might be a redirect? I noticed that in some other regions, the direct feed URL points to different regional hostnames -- maybe this could explain the difference between the results before.

Can you run the following using your map's NAME (and be sure to redact the NAME in the output if you don't want it visible here):

curl -sv https://explore.garmin.com/Feed/Share/NAME 2>&1 | grep -i location
BHSPitMonkey commented 6 months ago

If that turns out to be the issue, I have a change in main that may fix it. You can try it out by going to HACS -> Integrations -> Garmin MapShare -> menu (top-right corner) -> Redownload and select the version main.

BHSPitMonkey commented 6 months ago

Version v1.0.1 includes that change as well as better logging / error handling messages; Hopefully these can help track down the problem.

BHSPitMonkey commented 6 months ago

@LW-Ho - I've just tagged version v1.1.0 with a new base URL, which I believe may fix this issue for non-USA accounts. Please update using HACS and let me know if that works!

Thank you very much! This version successfully connects now! Forgot to mention, my account is under the name Taiwan. Also, grateful to the author for identifying this issue.
