getting request logging config failed.

Error message

getting request logging config failed. %v

What it means

ParseHTTPOptions reads the request-logging YAML config from an extflag.PathOrContent and wraps any failure to obtain that content with this message. It indicates the file/flag pointing at the HTTP logging config could not be read or resolved.

Solutions

1. Check the path/flag value passed to the request logging config extflag and correct it
2. Verify the file exists and is readable (ls -l / cat the file)
3. If inline config is intended, pass the content via the flag's inline syntax instead of a file path
4. Inspect the wrapped %v cause printed with the message for the underlying OS error

Example fix

// before
logOpts, err := ParseHTTPOptions(extflag.NewPathOrContentOrEmpty("bad/path.yaml"))
// after
if _, err := os.Stat("config.yaml"); err == nil {
    logOpts, err := ParseHTTPOptions(extflag.NewPathOrContent("config.yaml"))
}

if p := flagValue; p != "" {
    if _, err := os.Stat(p); err != nil {
        return fmt.Errorf("request logging config not readable: %w", err)
    }
}

When it happens

Trigger: Calling ParseHTTPOptions with a PathOrContent whose path does not exist, is unreadable, or whose --http-req-log-config style flag was passed incorrectly.

Common situations: Typo in the config file path passed on the CLI; file mounted but missing in a container; insufficient read permissions on the YAML file.

Understand the failure class

Background: "failed to read file", EACCES, ENOENT and "could not read <path>" errors: when a program can't read a file from disk — this error's family across 49 libraries.
