relayout throws error when updating axis using object syntax

[bpostlethwaite]

A call to relayout using object relayout syntax that looks something like:

layoutUpdate = {"xaxis2.domain[1]":0.7575000000000001,"xaxis3":
 {"anchor":"y2","domain":[0.7925,0.95]}}
Plotly.relayout(graphDiv, layoutUpdate)

will throw

uncaught TypeError: Cannot read property 'type' of undefined
    at convertCoords (convert_coords.js:30)
    at _relayout (plot_api.js:1975)
    at Object.relayout (plot_api.js:1721)
    at HTMLAnchorElement.<anonymous> (index.js:3580)
    at HTMLAnchorElement.dispatch (toolpanel-dependencies-bundle.js:2003)
    at HTMLAnchorElement.u (toolpanel-dependencies-bundle.js:1927)

when called on a normal single axis plot.

It appears to be thrown in the relayout code during some Annotation coord call. Perhaps because xaxis2 doesn't exist?

Note that using plotly.js's infamous dot syntax

layoutUpdate = {"xaxis2.anchor":"y2","xaxis2.domain":[0.6,0.95],"yaxis2.anchor":"x2","yaxis2.domain":[0.6,0.95]}
Plotly.relayout(graphDiv, layoutUpdate)

seems to work correctly.

I am updating code that uses object syntax to use dot notation as a workaround.

This one is probably for @alexcjohnson :)

I think I fixed that one in #1494

yep looks like it. I'm going to close it - feel free to open it up and double check if you are feeling suspicious.
