+1 - I ran in to the same issue starting today without changing any of my TSS code, but bumping to the latest TSS version I hacked the vinxi package to solve this In node_modules/vinxi/lib/dev-error.js changed 
setResponseHeader(event, "Content-Type", "text/html; charset=UTF-8");
setResponseStatus(event, 503, "Server Unavailable");
setResponseHeader(event, "Content-Type", "text/html; charset=UTF-8");
setResponseStatus(event, 503, "Server Unavailable");
to add the IF statement and have this: 
if (!event._handled && !event.node.res.headersSent) {
    setResponseHeader(event, "Content-Type", "text/html; charset=UTF-8");
    setResponseStatus(event, 503, "Server Unavailable");
}
if (!event._handled && !event.node.res.headersSent) {
    setResponseHeader(event, "Content-Type", "text/html; charset=UTF-8");
    setResponseStatus(event, 503, "Server Unavailable");
}
