coords must be in "x,y" format (e.g. "1,2")

Error message

coords must be in "x,y" format (e.g. "1,2")

What it means

normalizeCoords() splits a coordinate string on commas and requires exactly two trimmed parts, which it then forwards to normalizeNumber as x and y. It throws ArgumentError when the input does not have exactly two comma-separated components, because GeoGebra point placement needs both an x and a y value.

Solutions

1. Pass coordinates exactly as 'x,y' with a comma separator and no extra components (e.g. '1,2').
2. Use '.' as the decimal separator: '1.5,2.5' not '1,5 2,5'.
3. If data is an array or object, join it first: [x, y].join(',').
4. Validate the format before calling: /^\s*-?\d+(\.\d+)?\s*,\s*-?\d+(\.\d+)?\s*$/.test(coords).

Example fix

// before
await placePoint({ coords: [1, 2] });
// after
await placePoint({ coords: '1,2' });

const COORD_RE = /^\s*-?\d+(\.\d+)?\s*,\s*-?\d+(\.\d+)?\s*$/;
if (!COORD_RE.test(coords)) throw new Error('coords must be "x,y", e.g. "1,2"');

null

try { await placePoint({ coords }); } catch (e) { if (String(e.message).includes('x,y')) { console.error('Use format "1,2" with a comma and decimal points, not commas'); } else throw e; }

When it happens

Trigger: Calling any point-creating tool with coords like '1' (missing y), '1,2,3' (extra component), '1;2' (wrong separator), or an empty string — parts.length !== 2 triggers the throw.

Common situations: Users typing coordinates with a space+comma only ('1 ,'), using locale decimal commas ('1,5,2,5' for two decimals), or passing a JSON array instead of the documented 'x,y' string.
