Analyze external stack traces
You might want to analyze exceptions received by someone else, for example, QA engineers, or investigate a deadlock, or a hang-problem. Unlike the exceptions that you get in the debug mode or when running unit tests, these exceptions do not have links that help you navigate to the corresponding locations in the source code.
With WebStorm, you can copy an exception or full thread dump, paste it to the Stack Trace Analyzer, explore information, and navigate to the corresponding source code.
In the Analyze Stack Trace dialog that opens, paste the external stack trace or thread dump into the Put a thread dump here: text area.
If you want to explicitly specify the directory with the corresponding dSYM files, select the Use additional directory to search for missing dSYMs checkbox and enter the desired directory in the field or choose it from the file system.
Click OK. The stack trace is displayed in the Run tool window.
To jump to the code that caused the problem, scroll to the stack trace line you need and click the link to the source file. The file opens in the editor.
