stylefunction.js' fromTemplate might receive an array about ol-mapbox-style HOT 10 CLOSED

It looks like the returned value is an array even if the label is defined as a single string field (i.e. without a function like to-string).

["get", "<attributeName>"]

Moreover, there are a lot of other functions available, like length, match, any, etc.

Have you tried this with latest master? #86 added support for these expressions, so your styles should work now.

That's great news.

Sadly I could not try the latest master as both npm i ol-mapbox-style@latest and npm i in a freshly cloned repo fails with

./util/has_lib.sh: line 31: pkg-config: command not found

on macOS.

Sorry, I meant npm i boundlessgeo/ol-mapbox-style not npm i ol-mapbox-style@latest.

That's the canvas dev dependency. Try npm install --production ol-mapbox-style@beta.

After installing pkg-config and cairo w/ Homebrew both install methods work just fine.

However, I'm back to square one, as I get the same error even with [email protected].

Can you share a validated style document that triggers the error?

from ol-mapbox-style.

Sure thing - style.json.zip.

Validates fine against mapbox-gl-style-spec v12.0.0.

Thanks @aberenyi. I just pushed d605f0d and released v3.0.0-beta.9. The problem was that we tried to convert expressions to expressions.

Can you please verify that things work now and report back?

Works like a charm - many thanks @ahocevar!
