Column '{colId}' template uses unknown pipe '{name}'. Built-in pipes: {list}. Register others with config.pipes.

What happened

A template applied a pipe that is neither built in nor registered, so the pipe resolves to nothing and the value passes through unpiped - the cell shows the raw value where you expected it formatted.

The fix

Use one of the built-ins listed in the message, or register your own with config.pipes.

The smallest fix

createGrid(el, { pipes: { initials: (v) => String(v).split(' ').map((w) => w[0]).join('') } });
