internal relayout method called with undefined

We have observed a relayout failure immediately after this warning:

WARN: Relayout fail. undefined undefined
Non-Error promise rejection captured with value: undefined

coming from: https://github.com/plotly/plotly.js/blob/24b6f75e2d3b58cb1cd9cdd850894720404373d3/src/plot_api/plot_api.js#L1774

I'm not sure which exact circumstances triggered this failure, but the relayout internal function probably should not reject if astr is undefined, as this simply means there is nothing to update (recording the warning seems fine as it helps to diagnose call sites which are not correctly omitting the relayout, but it should not cause the function to fail).

I suggest that this branch should return successfully after logging a warning if astr is undefined / null.

It would also be useful for diagnosing the root cause further if the warning could include a stack trace.

Commencez dans src/plot_api/plot_api.js autour de la ligne 1774 et suivez la manière dont une valeur undefined ou null de astr atteint la fonction interne relayout. Vérifiez le comportement de l’avertissement et confirmez que ce chemin s’achève correctement plutôt que de rejeter ; examinez comment une stack trace faciliterait le diagnostic et vérifiez le comportement pertinent de relayout avant de définir l’achèvement.
