It looks right, the only difference from my code is that I use float[] instead of buffers but that shouldn't make a difference. Given the error description I would bet that it is a typo somewhere :-)

Is the shader linked without errors? Are you sure you actually pass in the correct programId? That's where I would start looking after checking the obvious things you already checked.
