Deploying a Minimal API using plumber on DigitalOcean

Hello! I try to deploying a minimal API using plumber on DigitalOcean https://www.r-bloggers.com/deploying-a-minimal-api-using-plumber-on-digitalocean/

I followed the all instruction steps thoroughly After command id <- do_provision() I have an error (Error: Region is not available), here is the log

THIS ACTION COSTS YOU MONEY! Provisioning a new server for which you will get a bill from DigitalOcean. Waiting for authentication in browser… Press Esc/Ctrl + C to abort Authentication complete. Using default ssh keys: Error: Region is not available In addition: Warning message: You have not specified any ssh_keys. This is NOT recommended. (You will receive an email with the root password in a few minutes

Why is my region is not available?

Thank you, Jarland!

I managed to go a little further. I needed to provide region as an argument. But I still could not deploy Plumber. Here is the log and traceback:

Hey friend,

I’m not an expert on this software, but I did some digging and I found a tip on how to expose debugging data from here: https://github.com/trestletech/plumber/issues/224

It seems that running “traceback()” can gather more information. Could you do that and let us know a bit more about the variables behind this attempt to create a droplet?
