What does "Zipping with concurrency: Infinity" means?

while running deploy, the last line in the log is " Zipping with concurrency: Infinity" and then it hangs forever. does anyone know what that means? google returns nothing…

Does this occur with a default serverless.yml such as one of the more trivial examples ?

Are you on Windows/Linux/Mac ? What O/S Node version ?

The “Infinity” value might be due to a misconfiguration or a bug in the deployment tool, where it’s attempting to use an infinite number of threads/processes to zip files.
Check the deployment configuration (like .yaml, .json, or config.js files) for any settings related to concurrency, parallelism, or zipping processes. Look for a field that might be set to an invalid value (like Infinity or undefined).

Have you checked for any updates or bug reports related to the deployment tool that might address issues with infinite concurrency or hanging during the zipping process?
