jsonvalidate fxn, error message clarification

[sckott]

@ateucher not sure how to interpret this message:

geojson_validate('{ "type": "FeatureCollection" }', error = TRUE)
#> Error: 1 error validating json:
#>  - data: no (or more than one) schemas match

what does no (or more than one) schemas match mean?

with another fxn I get

geojson_hint('{ "type": "FeatureCollection" }', error = TRUE)
#> Error: Line 1
#>     - "features" property required

It looks like it's generic message from is-my-json-valid when one of the required fields in the schema isn't there. See mafintosh/is-my-json-valid#82 and mafintosh/is-my-json-valid#38. Apparently it's when a field defined in the schema by oneOf or anyOf doesn't fit or isn't present (such as the geometry type??). Unfortunately if is-my-json-valid isn't going to be more specific, I don't think we can be either.

[sckott]

okay, but we know it is helpful for some errors at least. And I imagine we can get an improved schema at some point?

I'll add to docs that some errors won't have specific messages. But this option fast, so there's a tradeoff there

[ateucher]

Yup, it is helpful for some errors... and it is fast. I'm not sure if the problem is with the schema, or with the reporting from is-my-json-valid - judging from the comments in those issues, it could be done better. But I'll keep my eyes out for a better schema, or ways to improve the current one...

Ah right! Well either way, it may improve
