This doesn't seem like a security issue, and I'm not sure whether this bug presents anything actionable at all.

in which cases can an error without message occurred?

Hi, I'm unsure if this is the correct component for this issue but I think Core > DOM is a good place to start, please feel free to change the component to a better suited one.

Jan, could you take a look? Thanks.

It's probably an internal error code that we don't have a detailed message for.
For example, NS_ERROR_DOM_QUOTA_REACHED translates to "Persistent storage maximum size reached", but NS_ERROR_OUT_OF_MEMORY translates to "".
Change error.message to error.name in your logging function and you should be able to see the error code.
