Unconnected custom nodes with multiple output ports throwing warnings

[andydandy74]

Dynamo version

2.0.1 stable

Operating system

Windows 10

What did you do?

Placed a custom node with multiple output ports on canvas

What did you expect to see?

No warnings

What did you see instead?

Warnings. Every input port will generate a List indices must be numeric warning.
This is a regression. Nodes like these don't throw warnings in 1.3.x

Hi @andydandy74 Verified that this is a regression. Thanks for logging this issue.
Note that the warning goes away when "a" is assigned a value.

This is actually weird:

1. If you remove the CBN and custom node connection (shown in the screenshot above), the warning re-appears. Note that I do see the values in the custom node preview bubble
2. In 1.3.x the custom node output is a list and in 2.0.x, it's a dictionary

@smangarole I think @aparajit-pratap just fixed this here:
#8928

@aparajit-pratap is this the same issue?

[aparajit-pratap]

Yes @mjkkirschner this should have been fixed in #8928. @smangarole could you test if this still reproduces in master (2.1.0)? Thanks.

[smangarole]

Fixed in the latest daily build. Closing @jnealb @mjkkirschner @aparajit-pratap @andydandy74
