must contain three finite numbers.

Error message

${keyword} must contain three finite numbers.

What it means

DOMAIN_MIN and DOMAIN_MAX headers in a .cube file must each contain exactly three finite numbers defining the LUT input domain. parseCubeLut throws when the line has a different count of values or contains non-finite numbers (NaN/Infinity).

Solutions

1. Rewrite DOMAIN_MIN/DOMAIN_MAX lines to exactly three finite numbers, e.g. 'DOMAIN_MIN 0 0 0' and 'DOMAIN_MAX 1 1 1'.
2. Remove the DOMAIN lines entirely if the default 0–1 domain is intended (they are optional).
3. Re-export the LUT from a compliant tool.
4. Check the reported line for missing or corrupted numeric values.

Example fix

// before
DOMAIN_MIN 0 0
// after
DOMAIN_MIN 0 0 0

for (const line of text.split('\n')) {
  const m = line.match(/^DOMAIN_(MIN|MAX)\s+(.*)$/);
  if (m) {
    const nums = m[2].trim().split(/\s+/).map(Number);
    if (nums.length !== 3 || !nums.every(Number.isFinite)) throw new Error(`Bad ${m[1]} on: ${line}`);
  }
}

null

try {
  parseCubeLut(text);
} catch (err) {
  if (err.message.includes('must contain three finite numbers')) {
    // fix or drop the DOMAIN line (defaults apply)
  }
}

When it happens

Trigger: Loading a .cube file with lines like 'DOMAIN_MIN 0 0' (two values), 'DOMAIN_MAX 0 0 0 0' (four values), or values parsing to NaN/Infinity (e.g. 'DOMAIN_MIN 0 0 inf').

Common situations: Non-standard LUTs exported with 2- or 4-component domain lines; corrupted files where a value was dropped; typos like 'Infinity' text in the header.
