ExternalError: TypeError: a is null caused by Skulpt?

[nerd01]

I guess Skulpt does not support merge of two dictionaries like in {**dict1, **dict2}, which causes the error?

[p.colbert]

Is it possible that in this case, your dict1 or dict2 is not actually a dict? You can check by printing their types.

Correct. Skulpt does not yet support this. See this feature request which also gives a suggested work around.

Request: catch internal error on dictionary unpacking (PEP 448)

Oh, BTW, in case anyone tried this and failed, you can still merge dictionaries on a single line. merged_dict = dict(dict_a, **dict_b)

The good news is that we have a contribution in the pipeline to fix this within Skulpt.

We’ll update the above feature request when this goes live in anvil.
