Failed requests for B10

Any time I try to call WCS or FIS request that includes B10 I get following error: Failed to evaluate script. If I exchangge the B10 for anything else, it works fine. May I missing something about this particular band? Thanks a lot.

Here is the link, I purposely did not include the key.

Here comes the identification of the layer in my configuration utility:
let viz = new Identity();

function evaluatePixel(samples) {
let val = samples[0].B10;
return viz.process(val);
}

function setup(ds) {
setInputComponents([ds.B10]);
setOutputComponentCount(1);
}
