Invalid LUT content on line

Error message

Invalid LUT content on line ${lineNumber}: DOMAIN_MIN may only be declared once

What it means

This TypeError is a structural validation failure in the .cube LUT parser: within parseCubeLut, the DOMAIN_MIN directive is a global header that defines the input domain's lower bound, so it is only meaningful once per file. The parser tracks a hasDomainMin flag, and fires this error the second time a DOMAIN_MIN line is encountered in the same .cube file. It indicates the LUT file itself is malformed (duplicate header), not a problem with the caller's code; the fix is to correct the LUT file so it declares DOMAIN_MIN at most once.

Solutions

1. Remove the duplicate DOMAIN_MIN line, keeping a single declaration
2. Edit the existing DOMAIN_MIN values in place
3. Re-export the LUT from the original tool

Example fix

// before
DOMAIN_MIN 0 0 0
DOMAIN_MIN 0.1 0.1 0.1
// after
DOMAIN_MIN 0.1 0.1 0.1

const mins = content.split(/\r?\n/).filter((l) => l.trim().startsWith('DOMAIN_MIN'));
if (mins.length > 1) throw new Error('Duplicate DOMAIN_MIN');

null

try {
  const lut = parseCubeLut(content);
} catch (e) {
  if (e instanceof TypeError && e.message.includes('DOMAIN_MIN may only be declared once')) {
    // dedupe DOMAIN_MIN lines and retry
  } else throw e;
}

When it happens

Trigger: parseCubeLut() receives content with two DOMAIN_MIN lines, e.g. 'DOMAIN_MIN 0 0 0' followed by 'DOMAIN_MIN 0.1 0.1 0.1'.

Common situations: Hand-edited files where the domain was changed by adding a line instead of editing, or concatenated LUT files.
