[question] HTTP 401 error when following the examples and guides about harp.gl HOT 10 CLOSED

@trusktr , thanks again for looking into this.

I notice that we can simplify the interface, why should you need to specify the authenticationMethod, when the format could decide... or at least the format supplies a default authentication method, which could be this apikey, see getDefaultAuthMethod on OmvRestClient

I created an issue so that we can simplify this for others: #1390

from harp.gl.

method: harp.AuthenticationMethod.QueryString

from harp.gl.

I also just tried to make a REST app ID, then an API key for that, but no luck. For example:

GET https://xyz.api.here.com/tiles/herebase.02/14/12919/8134/omv?access_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 401

from harp.gl.

Okay, looks like I actually need to go to HERE Studio Token Manager, not the regular Here app and api key manager, which can be confusing.

However, I've no idea how to generate a token. When I try, it says

No rights are selected for the token generation!

which isn't helpful.

I'm stuck here with no idea how to make a token to try the lib. Surely this is an annoying user experience for people who've tried what I'm trying. Don't take it personally, it's just that after spending the time to get Harp without Webpack, now I can't actually run the code for reasons unknown and not related to the code.

That UI is not intuitive: one needs to select check boxes in the table, which is seemingly unrelated to the popup form. This is a bad user experience because it is not obvious that checkboxes must be selected before opening the popup form. Those checkmarks seem like they are for managing entries in the tables, but there are no entries in the tables to begin with, so a person would not automatically think to start to interact with an empty table in order to start making tokens.

After I figured this out, I selected some check marks, and when I click the final Generate Token button in the popup window (after filling out the fields appropriately, as far as I know), nothing happens and the Google Chrome console shows the following error:

Uncaught TypeError: Cannot convert undefined or null to object
    at Function.entries (<anonymous>)
    at generateToken (tokenmatrixui.html:1277)
    at HTMLElement.onclick (tokenmatrixui.html:268)

@trusktr , thanks for your bug report, and I apologize for your frustration.

We just recently changed away from xyz to the vector tile service, see: ae5f191

How did you generate the key, I guess you used this guide: https://github.com/heremaps/harp.gl/blob/master/docs/GettingStartedGuide.md#-here-credentials ?

If you change your baseUrl to the vector tile service, with the original key, does it work? See: https://github.com/heremaps/harp.gl/blob/master/docs/GettingStartedGuide.md#attach-data-source

Again sorry about this and thanks for your involvement!

Hello Jonathan, thanks for the help. I tried setting baseUrl to https://vector.hereapi.com/v2/vectortiles/base/mc, then I get the errors

GET https://vector.hereapi.com/v2/vectortiles/base/mc/14/12919/8133/omv?access_token=XXXXXXXXXXXXXXXXXXXXXX 401

with XXXXXXXXXXXXXXXXXXXXXX being the api key.

For reference, this is the page where that key came from,

from harp.gl.

Ok! It worked. It needed the following (which ironically I realized in your comment in the Webpack issue).

        baseUrl: "https://vector.hereapi.com/v2/vectortiles/base/mc",
        authenticationCode: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
        authenticationMethod: { // <------------------------ This was missing.
            method: AuthenticationMethod.QueryString,
            name: "apikey"
        },
