Cannot show error in Configuration window

Hi
Im trying to add errors to OptionsFlow

class OptionsFlow(OptionsFlowWithConfigEntry):

    async def async_step_init(self, user_input: dict[str, Any] | None = None) -> FlowResult:
        errors = {"base": "test error"}

        data_schema = vol.Schema({
                vol.Required(CONF_USERNAME): cv.string,
                vol.Required(CONF_PASSWORD): cv.string,
            })

        return self.async_show_form(step_id="init", data_schema=data_schema, errors=errors)

But I got empty error field
screen

Could you help me please?

Did you add the key in the translation file?

Yes, And it is the same nothing shown :frowning: Only red line.

Actually, I have tried to use it in ConfigFlow without adding the key in the translation file like this

class MyConfigFlow(ConfigFlow, domain=DOMAIN):

    async def async_step_user(self, user_input: dict[str, Any] | None = None) -> FlowResult:
        errors = {"base": "test error"}

        data_schema = vol.Schema({
                vol.Required(CONF_USERNAME): cv.string,
                vol.Required(CONF_PASSWORD): cv.string,
            })

        return self.async_show_form(step_id="init", data_schema=data_schema, errors=errors)

And it works.
But for OptionsFlowWithConfigEntry it doesnt work. I dont know why
