Null attributes causes the highlight component to throw errors

Bug: What is the current behavior?
I have homeowner records in Algolia, and sometimes the owner_name can be NULL, when that's the case, the ais-highlight will throw this error over and over:

Error in render: "Error: The "owner_name" attribute is currently not configured to be highlighted in Algolia. See https://www.algolia.com/doc/api-reference/api-parameters/attributesToHighlight/."

Bug: What is the expected behavior?
No text is displayed for that attribute, no error is thrown. The attribute is set up for searching, one or two records just have null values!

Bug: What browsers are impacted? Which versions?
All

Bug: What is the proposed solution?
Not sure... Change this check to something more strict though: https://github.com/algolia/vue-instantsearch/blob/master/src/components/Highlight.js#L22

I think at a very minimum, the error message should be clarified, because it sent me down the wrong path for an hour or two trying to figure out why it wasn't "configured for highlighting".

Seems like in your case, just changing that error to “might” and into a warning should be enough I think

Feel free to make a PR to any text you’d prefer!

I think that better solution is for the ais-highlight component to happily display null values.

I also have the same issue for null attributes to be highlighted.

@ligne13 this has already been fixed, can you make a codesandbox of what goes wrong? There's a template here
