Accepting any input on an custom node input?

[darkpixel]

I've dug around the code and can't really find an authoritative source for input types.
You can figure out from examples and other custom modules about accepted input types for things like STRING, INT, FLOAT, BOOL, etc...

I had a custom node that had an input type of "*". I would look at whatever the input was (string, float, array, etc...) and do stuff with it. I would output a STRING for use in the workflow.

It's worked fine for the last year. But a recent change (some time in the last 30-90 days) now causes the console to throw:

 - Return type mismatch between linked nodes: evaluate_input <whatever data was input>  != *

I've tried setting the input to "" and "ANY" and "ALL". Nothing works.

How can I tell ComfyUI that I want to accept anything under the sun as input?

Also...I think it would be good to have a list of common standard input types that are generally accepted.

"*" was never actually allowed. If it worked, it was likely in a blind spot of the validation.
To bypass this, custom node developers are using the any_typ trick.

Does this work with types other than "*" (e.g. "INT,FLOAT" for any numeric input)? Also, does it work with the native get/set nodes?

[ltdrdata]

A wildcard input allows any type of connection.

In the case of primitive nodes, connections are not allowed if the input type is not a primitive type, as this is restricted by the primitive node itself.

In my node pack, once a connection is made, I employ a method that forcibly assigns a type. After the type is assigned, the structure becomes one where connections are possible.

Thanks for the pointer @ltdrdata. I was able to get things working!
