MARKLESS_ELEMENT_HANDLE_UNBOUND

element() handle is read before it is bound: a Markless compiler error.

Error or warning from the compiler, while it builds your .tsrx files.

What happened

Markless prints the message, the reason, and a suggestion:

MARKLESS_ELEMENT_HANDLE_UNBOUND: Reading element handle "<source>" will produce undefined because "<handleName>" is never bound with el={<handleName>} in this component.
element() handles are DOM locator references, not state. A read is only useful after the handle has a host element binding that resume can locate.
Bind the handle to one host element with el={handle}, or remove the read if undefined is intentional.
