An eFAST run with two parameters can fail with the wrong number of samples.
Expected behavior
Even if eFAST with 2 parameters is perhaps overkill, this should work.

Commit 15346901f00 (2026-04-09 19:20 UTC)
Build Info:
Official https://julialang.org release
Platform Info:
OS: macOS (arm64-apple-darwin24.0.0)
CPU: 16 脳 Apple M4 Max
WORD_SIZE: 64
LLVM: libLLVM-18.1.7 (ORCJIT, apple-m4)
GC: Built with stock GC
Threads: 1 default, 1 interactive, 1 GC (on 12 virtual cores)
Environment:
JULIA_PROJECT = @.
DYLD_LIBRARY_PATH = :./addons/libRoadrunner/roadrunner/lib
Additional context
A different error occurs if you replace samples=500 with samples=50. I will open a PR shortly on both.
