Error message
failed to parse HTTP account
What it means
Thrown when json.Unmarshal of a users entry into HTTPAccount fails. After parsing the protocol.User envelope, Xray unmarshals the same JSON object into HTTPAccount (username/password fields); if those fields have wrong types (e.g. username as a number) or the JSON is malformed, this error is returned with the parse error attached. Only hit on the servers[].users form.

Solutions
- Ensure username and password in each users entry are JSON strings
- Use the documented field names for HTTP outbound users
- Validate the raw JSON with jq before starting Xray
Example fix
// before
"users": [ { "user": 123, "pass": "x" } ]
// after
"users": [ { "user": "123", "pass": "x" } ] Defensive patterns
Strategy: validation
Validate before calling
var probe struct {
Username string `json:"user"`
Password string `json:"pass"`
}
if err := json.Unmarshal(rawUser, &probe); err != nil {
return fmt.Errorf("HTTP account fields must be strings: %w", err)
} Prevention
- Always quote credentials in JSON even when they look numeric
- Use the field names expected by Xray's HTTPAccount (user/pass per docs)
When it happens
Trigger: A users entry like {"user": 123} where the username field is numeric, or extra structure that breaks deserialization of username/password into strings.
Common situations: Using key names from other ecosystems (e.g. "user" vs expected account field names) combined with wrong value types; templating bugs injecting non-string credentials.
