The python code reports an error and cannot locate the specific location

[y1y2]

python code reports an error, but it cannot locate the specific line and can only reach the specific function. However, javascript can

def multiSite(ctx):
    tc = base.traceContext()
    req = base.parseJsonString(ctx.getBodyAsString())
    base.logInfo(tc, f"ceshi,{ req['AAA']}")

Hi. It's a known issue that the Java stacktraces don't show the location well, unfortunately it's very hard to fix. You can catch the exception and use the python exception printer to get a python traceback. Like this:

try {
    context.eval("python", ... your code);
} catch (PolyglotException e) {
    Value formatException = context.eval("python", """
            def _format_exception(e):
                import traceback
                return ''.join(traceback.format_exception(e))
            _format_exception
            """);
    System.out.print(formatException.execute(e.getGuestObject()).asString());
}
