Exception occurred: line 174, in _formal_params KeyError: 'name'

Hello, I'm getting this error when trying to do the following:

Cryptosee
========

Attribute Encryption
--------------------

.. js:autofunction:: encrypt

I've been able to generate documentation before and this is how the function is commented:

/**
 * Function that creates a symmetric key, encapsulates it and uses it to encrypt a ciphertext
 *
 * @param inPK {pem hexString} - PEM Hexadecimal representation of the receipient's public key
 * @param inPlaintext {String} - String of the data we want to safeguard
 * @param inAuthenticatedData {} -
 * @returns {}
 *
 */
const encrypt = (inPK, inPlaintext, inAuthenticatedData) => { ... }

KeyError: 'name'

Thank you for your help in advance!

Start with sphinx_js/renderers.py at _formal_params, line 174, and reproduce the Sphinx build using the JavaScript encrypt example and its @param annotations. Inspect the doclet passed to AutoFunctionRenderer for the missing field; done means the documented function builds without the reported KeyError and the resulting parameters remain represented correctly.
