IW3 missing when downloading product from Data Space

We’re also facing this issue. I went through the code with the debugger and javax.imageio.ImageIO encounters the following exception when trying to read the IW3 file: java.util.zip.ZipException: invalid LOC header (bad signature)

I’ll also log a ticket on the Copernicus Data Space Ecosystem, because this might be something they have to on their end.

I am facing exactly same issue.

Could you provide some information about your SNAP version?
