I got

An error occured during the execution of the overpass query!
This is what overpass API returned:



<p><strong style="color:#FF0000">Error</strong>: line 1: parse error: An empty query is not allowed </p>

@bhousel Hi Bryan. Do you know who can fix the tutorial? In https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL I couldn't find a minimal example.

Hi Bryan. Do you know who can fix the tutorial?

Sorry I don't know! It looks like this is no longer maintained.

[abitrolly]

Nobody from @osmlab who know how it works?

@abitrolly This issue is fixed in pull request #22.

/cc @bhousel @Secretmapper @tyrasd I would be happy to become maintainer of LearnOverpass. Please see pull requests #21 and #22 which restore main functionality.

After restoration work I have the following plan:

• fix non-critical errors and issues
• do a code cleanup
• port to upstream i18n support in Hugo
• ask community for exercise translations

Thanks @irnc , I've invited you to be the maintainer for the project!

This issue was fixed by 34e352d.

Fix was deployed to https://osmlab.github.io/learnoverpass/en/, so feel free to use it, but keep in mind that we have another known issue #24 which sometimes causes Run Query button to be disabled. Until it is fixed, please use LearnOverpass in non-incognito mode and refresh page when Run Query button is disabled on initial page load.

[abitrolly]

I hit #24 too and had to refresh the page.

The initial query is invalid and gives the error.

What is the valid minimal query to insert on the first page?

[irnc]

First exercise is solved by the following query:

node(48.5657094, 13.4490548, 48.5662416, 13.4501676);
out;

If you already tried it, please try again ;) as a fix for #25 was just deployed. That issue prevented almost all exercises to pass.

[Secretmapper]

Thanks @irnc! Apologies for the late reply, I've caught the flu last week.

It looks like you have access to the repo now ^_^ Let me know if there's anything else you might need from me

[abitrolly]

There is still the error on the map when the page is loaded. Starting tutorial with the error is not a good user experience, because you can never tell if the error is intentional, or it is a broken tutorial. I suspected a broken tutorial after overpass syntax change, that's why I asked for a minimal valid query.

Another problem is that syntax like node(48.5657, 13.44, 48.5662, 13.45); is perfectly valid, and the map renders successfully, but the error message is misleading:

If the syntax is right, I would expect it to say "The syntax is correct. Try to enter exact GPS coordinates to pass to the next exercise.".

@Secretmapper Thanks! Hope you are doing well. I will work on the roadmap soon to make project better prepared for new contributors. I would be glad to receive feedback on it once it is drafted.

@abitrolly Thanks for feedback, these are all good points! Could you please extract them into separate issues, so they could be worked out independently?

[abitrolly]

@irnc moved the aforementioned points into #32 and #33.
