`block run` unresponsive

[Mike_Pennisi]

In the “hello world” tutorial, the command block run runs indefinitely without reporting anything to standard output.

I’ve collected some debugging information regarding the Express npm module via the DEBUG environment variable:

If I ignore this issue and continue with the tutorial by entering https://localhost:9000 as the block URL in Airtable, the block displays a “loading” indicator indefinitely, and the process reports the following:

I was able to successfully complete the guide when using a MacBook.

+1 I have the same exact problem, and I’m on Ubuntu 18.04 as well

[Mike_Pennisi]

@MacGregor_Thomson It looks like the block executable currently doesn’t
report a few critical errors. It’s hard to say whether you’re experiencing the
same bug as me, but it’s worth a shot.

Generally, the executable will exhibit this behavior if its “file watching”
mechanism fails. There are many ways this could happen; here are two
possibilities and steps you can take to work around them:

• you’ve exceeded the maximum number of files that your operating system is
  configured to allow. This may be because you’ve been running for a long time
  or because the default settings are too conservative. Resolution: restart
  your computer or follow this guide to configure your system to allow more
  “watched” files (that second option only applies for folks using GNU/Linux)
• you have a non-readable file or directory in your “block” directory.
  Resolution: claim ownership of all files in that directory. On Unix-like
  systems, you can do this from the command-line by running the following
  command in the “block” directory: chown -R $(whoami) . (that’s a period at
  the end)

[MacGregor_Thoms]

Thanks @Mike_Pennisi! Indeed I needed to increase the inotify limit

[Boaz_Sender]

I am running into the same issue on ubuntu 18 with node v12.11.1. I ran debug and got almost the same output talking about express router, but with my path info in the beginning.

[Boaz_Sender]

Your fixes got me up and running. I’m now up and running after chowing the block project directory and its contents, and updating my file watching limit. Thanks!
