MARKLESS_ELEMENT_HANDLE_DUPLICATE

element() handle is bound more than once: a Markless compiler error.

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

What happened

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

MARKLESS_ELEMENT_HANDLE_DUPLICATE: Cannot bind element handle "<handleName>" inside a keyed repeat because one authored handle would point at many row host elements. markless debugging playbook: run pnpm doctor, or read agent/markless.md in the installed @markless/core package
Each repeated row has its own DOM locator, so one handle declared as a single element cannot say which row it means.
Declare the handle as an ordered set by widening its type argument to an array - element<HTMLElement[]>() - written literally as T[], Array<T> or readonly T[]. Reads then answer every bound element in document order. Otherwise create a separate element() handle for each host element.
