invalid ssl option

Error message

invalid ssl option: %w

What it means

The 'ssl' (alias 'enablessl') URL parameter must be a boolean parseable by strconv.ParseBool (1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False). Any other value produces this wrapped error and aborts DSN parsing.

Solutions

1. Use ssl=true or ssl=1 to enable, ssl=false or ssl=0 to disable.
2. Trim whitespace/newlines from values sourced from environment variables before building the URL.
3. Normalize yes/on/enabled to true in whatever generates the connection string.
4. URL-encode the value if it may contain stray characters.

Example fix

// before
cassandra://host:9042?ssl=yes
// after
cassandra://host:9042?ssl=true

func parseStrictBool(v string) (bool, error) {
	b, err := strconv.ParseBool(strings.TrimSpace(v))
	if err != nil {
		return false, fmt.Errorf("%q is not a bool; use true/false/1/0", v)
	}
	return b, nil
}

func isParseBoolValue(v string) bool {
	_, err := strconv.ParseBool(v)
	return err == nil
}

cfg, err := parseCassandraConfig(dsn)
if err != nil {
	if strings.Contains(err.Error(), "invalid ssl option") {
		return fmt.Errorf("ssl must be true/false (not yes/on): %w", err)
	}
	return err
}

When it happens

Trigger: ssl=yes, enablessl=on, ssl="true " (with whitespace), or ssl=enabled in a cassandra:// URL.

Common situations: Using human-friendly booleans ('yes'/'on'/'enabled') from YAML/env config, whitespace from environment variables, or locale-formatted values.
