Process API Renderer Excepetion

Hello,

In some cases I receiving the following error at Process API:

{"error":{"status":400,"reason":"Bad Request","message":"Failed to evaluate script!\nevalscript.js:16: TypeError: Cannot read property 'B04' of undefined\n\t\t\t\t\treturn [ 2.5*samples[0].B04, 2.5*samples[0].B03, 2.5*samples[0].B02 ]\n ^\nTypeError: Cannot read property 'B04' of undefined\n at evaluatePixel (evalscript.js:16:29)\n at executeForMultipleScenes (:1153:14)\n","code":"RENDERER_EXCEPTION"}}

Is it something with my code or some API or image error?
it’s a little strange because in countless other polygons it works normally.

Thanks
