Error message

Cannot insert Service type configuration as additional login method.

What it means

UserConfig's update method inserts an additional login method for a user, but a Service-type configuration (API/service identity) cannot be added as an extra login method — only real user login variants are allowed. Inserting a UserConfig::Service returns this error and the map is left unmodified.

Solutions

1. Pass a non-Service UserConfig variant (e.g. Password or OAuth) to update
2. Handle Service configurations through the dedicated service-identity APIs instead of user login methods
3. Guard the call site: match on the variant and skip/handle Service before calling update

Example fix

// before
user_config.update(UserConfig::Service { .. })?;
// after
match &login {
    UserConfig::Service { .. } => { /* handle via service config API */ }
    _ => user_config.update(login.clone())?,
}

if matches!(login, UserConfig::Service { .. }) {
    return Err(anyhow!("Service config cannot be an additional login method"));
}

fn is_user_login(cfg: &UserConfig) -> bool { !matches!(cfg, UserConfig::Service { .. }) }

When it happens

Trigger: Calling user_config.update(UserConfig::Service { .. }) to add a Service config as an additional login method for a user.

Common situations: Misunderstanding which UserConfig variants are user login methods vs service identities; copying config-building code that constructs Service variants and passing it into update instead of a Password/OAuth variant.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
