What ReactJS error Minified React error #301 mean?

Question

I'm working on a ReactJS web app. I made a change to code that was working and now I get an error:

Error: Minified React error #301

I can revert the code to get it working again but I'm not sure what I'm doing wrong to get this error.

NOTE: The last thing I added was:

const [openDialog, setOpenDialog] = useState(false);

So perhaps I can't use this...

Does React have a list of error codes and explanations?

There should be a URL included in the error that points you to a more complete description. The pattern is:

https://reactjs.org/docs/error-decoder.html?invariant=###

So I plugged in 301 and got the following https://reactjs.org/docs/error-decoder.html?invariant=301 answer...

Too many re-renders. React limits the number of renders to prevent an infinite loop.
