Empty RSS feed response

[Figure-itout]

I live in The Netherlands, try to add someones mapshare-address. But get an error about empty response.

If I try to add the integration with a wrong password, I got the same error.

Can you go to the integration in HACS, select "Redownload" from the menu, and choose "main" as the version, and then restart HA and try again?

I tried the main version but got the same error.

Hi I'm not sure if it belongs here, but as my problem seems related I didn't want to open another Ticket. I'm a *n00b to has.io (As oppoesd to the Docker versions, that do not have direct access to HACS or these Addd-ons. So I don't know if its me, or not.

As it is I can not use my account share.garmin.com/Ichijoe + "MyPass", as it always returns "Unexpected Error", The other Garmin Connect Addon, for HA is working fine, with my eMail + Pass

*Any hints as to where (Or how), I can dig into the debug setting(s) would be appreciated,

[Figure-itout]

You can find the logs here (have to translate it from Dutch): Settings -> System -> Logs Here you can find the error of mapshare. Click on it for the details.

[BHSPitMonkey]

HACS works fine via Docker; That's the way I use it every day.

This integration does not use the username/password from your Garmin account, it uses the separate link name and password meant for sharing with friends and family in your MapShare settings.

To enable debug logging, try visiting YOURINSTANCE/config/integrations/integration/garmin_mapshare, click "Enable Debug Logging" there, and then view your logs in Settings > System > Logs after triggering another failure.

[BHSPitMonkey]

Version v1.0.1 is now released, with better logging / error handling messages. Give it a try (again, with Debug Logging enabled) and hopefully we can tell what's going on.

If there are still problems, and you're seeing your MapShare name/password function correctly on https://share.garmin.com/LINK_NAME_HERE, you can email me with your MapShare link name (and a temporary password, not your normal one) and I can try to reproduce the issue on my end (if you don't mind me potentially knowing where your inReach has been). My email can be found in the commit log.

[Figure-itout]

Thank you for the update. The error I get is: Server returned an empty response. This usually means the MapShare link name is not valid. Make sure you can successfully visit this map at: https://share.garmin.com/LINK_NAME_HERE

Debug logging doesn't show in the integration. I guess because a lack of an entity.

Can I use the e-mailadres at your old, unmaintained website?

[miggland]

I see the same behaviour as @Figure-itout

When I do this: curl -sv https://:MYPASSWORD@share.garmin.com/share/XXXXX

I get this response:

If I do this: curl -sv https://:MYPASSWORD@eur-share.explore.garmin.com/Feed/Share/XXXXX I get a result which looks like a sensible KML file.

@miggland Thanks! What happens when you drop the eur-share. part from that final URL (thus mimicking the request the integration makes)? Is there any indication in the response body/headers that suggests the need for a region-specific subdomain?

[BHSPitMonkey]

Progress! I was able to find a public MapShare feed based in Europe (side note, this guy is pretty extreme!) and learned that while accessing its feed using https://explore.garmin.com leads to an empty response, accessing its feed (or any other?) using https://share.garmin.com works as expected. There is probably some server-side logic that proxies requests from the share subdomain to the appropriate region, which is absent when you access one of the explore subdomains directly.

TL;DR: I've just tagged version v1.1.0 with the 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!

[Figure-itout]

That works for me! I am able to add the inreach of my friend. And the information is also correct.

[miggland]

Works now, thanks!
