Is code listing expected to work?

I like the theme very much, but I was trying to use the lstlistings (following the Overleaf documentation here), and it does not seem to work.

It just fails to compile ("compilation took too long"), for some reason 🙁.

Any idea why?

Just realized it fails with verbatim, too:

\begin{frame}{}
\begin{verbatim}
    blah
\end{verbatim}
\end{frame}

This time it shows an error message:

blah \end {verbatim} \end {beamer@frameslide}\ifbeamer@twoscreenstext \ETC.
! File ended while scanning use of \@xverbatim.
<inserted text> 
                \par 
<*> sample.tex
              
I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

Which brought me to this stackoverflow question, hinting towards making the frame "fragile" (whatever that means). This works:

\begin{frame}[fragile]
\begin{lstlisting}[language=Python]
import numpy as np
\end{lstlisting}
\end{frame}

That's great to hear you fixed it!
It appears that [fragile] is a necessity when using [verbatim] environment.

If you wish to use a {verbatim} environment in a frame, you have to add the option [fragile] to the {frame} environment.
