Invalid number of variables: ${problem.variables} (must be 1

Error message

Invalid number of variables: ${problem.variables} (must be 1-10000)

What it means

validateQuboProblem() found problem.variables outside the supported 1–10000 range. The solver allocates arrays sized by variable count, so zero, negative, or oversized problems are rejected up front before annealing begins.

Solutions

1. Correct the invalid input element reported in the message; validate the full input against the documented schema before submitting.
2. Add boundary validation so malformed input is rejected with a per-element diagnostic.
