Undefined data type

I was testing my block encoder and then I noticed that

Researching more, I found out that here

, all is not a text. Its data type is undefined:

Same for the other block:

This weird text causes an error when using . It is supposed to be a text, but for a reason, its data type is undefined. Is there any solution for this?

If something's data type is undefined, it probably means that thing isn't actually a text, but rather a JS object disguised as a text.

I'm pretty sure that's supposed to turn into "[all]".

And __shout__go__ for the other block
