Empty images for some queries of my custom configuration

[nastassia (Nastassia Barber)]

I have a configuration set up for my app that uses the pre-made functions for NDVI, RGB, and NBR with no edits for Sentinel-2 L1C data. For some reason, some queries that include a pretty wide date range (after 2015) return a blank image, whereas similar queries do not.

For example, this query with my config id entered returns an empty image:
https://services.sentinel-hub.com/ogc/wcs/{config-id}?SERVICE=WCS&REQUEST=GetCoverage&COVERAGE=RGB&BBOX=-13417289.382692268,6064912.140129407,-13408163.679269042,6074346.033810075&MAXCC=10&WIDTH=1000&HEIGHT=1000&FORMAT=image/tiff&TIME=2018-05-26/2018-06-23

Whereas this one returns the data I expect:
https://services.sentinel-hub.com/ogc/wcs/{config-id}?SERVICE=WCS&REQUEST=GetCoverage&COVERAGE=RGB&BBOX=-13417289.382692268,6064912.140129407,-13408163.679269042,6074346.033810075&MAXCC=10&WIDTH=1000&HEIGHT=1000&FORMAT=image/tiff&TIME=2018-09-01/2018-09-29

Does anyone know why this might be?

For completeness, here is the script:

//VERSION=3

let minVal = 0.0;
let maxVal = 0.4;

let viz = new HighlightCompressVisualizer(minVal, maxVal);

function evaluatePixel(samples) {
let val = [samples.B04, samples.B03, samples.B02];
val = viz.processList(val);
val.push(samples.dataMask);
return val;
}

function setup() {
return {
input: [{
bands: [
“B02”,
“B03”,
“B04”,
“dataMask”
]
}],
output: {
bands: 4
}
}
}
