`variantProperties` can also be a string

[flenter]

It can be set to Component set for node has existing errors. This happens when you have invalid/duplicate variant(names).

The type definition should be something in the line of:

  interface VariantMixin {
    readonly variantProperties: { [property: string]: string } | null | string
  }

or:

  // I am unsure if this is allowed in a type definitions file
  const VariantErrorMessage = "Component set for node has existing errors";
  interface VariantMixin {
    readonly variantProperties: { [property: string]: string } | null | typeof VariantErrorMessage;
  }

It seams everytime we have an error from Figma, variantProperties (that is deprecated btw) changes its type to string to bring error messages. I saw this occuring this week, when trying to get instances with conflict errors.

Because this question is related to a now deprecated API, I'm going to close this issue out. If you have issues with the new API componentProperties, please feel free to open a new issue.
