Hey everyone, I'm currently trying to implement user authentication with phone number using SMS sent code. I tried ory-copilot, but the issues never end. So, can you please help? My Kratos phone schema is as follows:

{
  "$schema": "<http://json-schema.org/draft-07/schema#>",
  "title": "Phone-Schema-v0",
  "type": "object",
  "properties": {
    "traits": {
      "type": "object",
      "properties": {
        "phone": {
          "type": "string",
          "format": "tel",
          "title": "Phone Number",
          "<http://ory.sh/kratos|ory.sh/kratos>": {
            "credentials": {
              "code": {
                "identifier": true,
                "via": "sms"
              }
            },
            "verification": {
              "via": "sms"
            }
          }
        }
      }
    }
  }
}

My kratos config is as follows (I tried adding templates wherever I can):

...

    ...
    code:
      enabled: true
      passwordless_enabled: true

But when I try to send this registration request:

curl --location '<http://localhost:4455/.ory/kratos/public/self-service/registration?flow=4aafa73b-7163-40d5-98af-6fdf8ea94645>' --header 'Content-Type: application/json' --header 'Accept: application/json' --data-raw '{"method": "code","traits": {"phone": "+201234567890"}}'

I get the following response:

{
  "error": {
    "code": 500,
    "status": "Internal Server Error",
    "reason": "Expected sms template but got <nil>",
    "message": "An internal server error occurred, please contact the system administrator"
  }
}

What do you think?

You may have forgotten to set

registration_code

in

courier/templates

Thanks @most-train-86113 for your suggestion.

registration_code

is not a valid field in my

courier/templates

config. If it's valid in your config, which Kratos version are you using? I'm currently using

oryd/kratos:v1.2.0

.

try this

courier

config @clean-piano-39737, this worked for me. (please modify base64 content according your needs)

Thanks @colossal-airline-19852 I resorted to handling OTP generation/verification and SMS sending outside Ory, and then logging in identities to Ory with generated passwords I'll definitely try your solution when I have time though.
