ORCA_PTY_BENCH_INGRESS_CHARS must be positive, received ${IN

Error message

ORCA_PTY_BENCH_INGRESS_CHARS must be positive, received ${INGRESS_CHUNK_CHARS}

What it means

Thrown by config/scripts/pty-batch-flush-benchmark.mjs when ORCA_PTY_BENCH_INGRESS_CHARS fails `!Number.isInteger(INGRESS_CHUNK_CHARS) || INGRESS_CHUNK_CHARS <= 0`. INGRESS_CHUNK_CHARS (default 65536) is the character size of each ingress chunk that the batched-flush benchmark feeds in. The guard at line 32-33 rejects non-positive sizes before the data-generation loop.

Solutions

1. Set ORCA_PTY_BENCH_INGRESS_CHARS to a positive integer (default 65536).
2. Unset it to accept the default.
3. Confirm you used INGRESS_CHARS (env name) and not INGRESS_CHUNKS.

Example fix

// before
ORCA_PTY_BENCH_INGRESS_CHARS=0 node config/scripts/pty-batch-flush-benchmark.mjs

// after
ORCA_PTY_BENCH_INGRESS_CHARS=65536 node config/scripts/pty-batch-flush-benchmark.mjs

const raw = process.env.ORCA_PTY_BENCH_INGRESS_CHARS
if (raw !== undefined && (!Number.isInteger(Number(raw)) || Number(raw) <= 0)) {
  throw new Error(`ORCA_PTY_BENCH_INGRESS_CHARS='${raw}' must be a positive integer`)
}

function isPositiveInt(value) {
  const n = Number(value)
  return Number.isInteger(n) && n > 0
}

When it happens

Trigger: Run the benchmark with ORCA_PTY_BENCH_INGRESS_CHARS set to `0`, a negative number, empty string, or non-numeric token. parseInt at line 10 returns NaN for garbage, and the line-32 guard throws.

Common situations: A developer confuses INGRESS_CHARS with INGRESS_CHUNKS and sets the per-chunk character size to zero, or forwards a blank value from a templated benchmark matrix. Note the env var name is ORCA_PTY_BENCH_INGRESS_CHARS while the constant is INGRESS_CHUNK_CHARS — a frequent mismatch.
