FORCDK-CORE-010
Thrown by a shared forty-cdk/core check, which reports under the primitive that ran it.
[forty-cdk/{primitive}] FORCDK-CORE-010: {piece} has no [{inputName}] binding.Cause
The input is declared optional so the parent can skip a piece whose binding is not written yet, which means a permanently unbound piece never joins its parent instead of failing to compile.
Fix
Bind [{inputName}] on every {piece}.
Where it comes from
projects/forty-cdk/core/src/unset-input/unset-input.ts:79
A value in braces is filled in when the message is reported, so the sentence in your console names the piece, input or value that failed.
