6 months ago Looks like Vega Editor is on Vega 5.25.0, but we're on 5.26.1. I'll have to find some time to rebuild Deneb with the older version to see if it's something to do with that, or if there's some other forces at work with how we're patching or parsing the spec in Deneb.

3 months ago Just an FYI that I'm running into this elsewhere too.

3 months ago To confirm, does "elsewhere" mean for other examples using Deneb or elsewhere in the Vega ecosystem?
Interim notes for me: I've had a quick look, and this seems to be an issue in both legacy builds and the newer versions (>= 1.6, which uses the revised parse/build workflow, and 1.7, which uses a further refinement to handle JSONC). The versions of Vega are in sync on 1.7 and Vega Editor currently also.
If we disable the explicit parse during spec processing and patching, Vega still fires this when the view initializes, so there doesn't seem to be any hacking around it to see if the spec will even render as it does in Vega editor.
For when I get a chance to pull on the thread some more, this is where the error is being raised in Vega.

3 months ago Thanks for the additional info - I'll try to see if I can zero-in on what's going on as soon as I get the bandwidth
Using Deneb standalone (Deneb_STANDALONE.1.6.2.20231207.0bcb9c6.pbiviz), the following spec produces an error but renders correctly in the online editor:
