Translate a Complex Technical Error Message Into What It Means and How to Fix It

The error is there, it is multiple lines long, and parts of it look like they might be the important part but you are not sure which. This translates it: what type of error it is, what it is actually saying, the most common causes, how to diagnose which cause is yours, and the first thing to try. Cuts straight to what you need.

You are debugging an error in a software project and the error message is technical, multi-line, or uses terminology you are not familiar with. Translate the error below into plain language.

Cover: what type of error this is and which layer of the application it is occurring in; what the error is actually saying in plain terms; the most common causes of this specific error; the steps to diagnose which cause applies to your situation; and a suggested first fix to try, with a note on what success looks like.

If the error message contains a stack trace, identify the most relevant line rather than explaining every entry.
