No argument passed to Plotly.register.

Error message

No argument passed to Plotly.register.

What it means

Guard at the top of Plotly.register: the function expects one module or a non-empty array of partial-bundle modules to add to the registries (traces, transforms, components, locales, apiMethods). The throw fires when register is called with no argument at all (undefined/null), which would otherwise cause a TypeError inside the module loop.

 *                          generally the keys should be the literal input strings, but
 *                          if default translations are provided you can use any string as a key.
 *  - format {object} : a `d3.locale` format specifier for this locale
 *                      any omitted keys we'll fall back on en-US.
 *
 *  A valid `moduleType: 'component'` module has fields:
 *  - name {string} : the component name, used it with Register.getComponentMethod()
 *                    to employ component method.
 *
 *  A valid `moduleType: 'apiMethod'` module has fields:
 *  - name {string} : the api method name.
 *  - fn {function} : the api method called with Register.call();

Solutions

1. Pass the module(s) to register, e.g. Plotly.register([require('plotly.js/lib/scatter3d')]).
2. Check that the import used to fetch the module actually resolved (a failed require yields undefined).
3. Register an array of modules when loading several partial-bundle pieces.
