Error message

The moduleSpecifier "%s" couldn't be retrieved from the resolved url "%s". Error : "%s"

What it means

Raised in Load when an https module specifier could not be read and the subsequent remote fetch also failed. The message wraps the original specifier, the final resolved URL, and the underlying fetch error, so it means the module exists at neither the local filesystem path nor the remote URL. The at-fault inputs are the specifier, the resolved URL, and the network error.

Solutions

1. Check that the resolved URL is reachable (open it in a browser/curl)
2. Fix network issues: DNS, proxy settings, TLS, or firewall blocking k6
3. Correct the import specifier if the resolved URL is wrong
4. Pin the module to an existing version/branch if the remote file was moved or deleted
