I'm sorry, but the provided knowledge sources do not contain information about viewing internal logs for a social sign-in when the data mapper is running in Ory Network. However, if you're encountering issues with the data mapper, it might be due to the social sign-in provider not returning all the data you expect. For instance, the user might not have given you permission to access their email address. In such cases, Ory will ask the user to fill in the missing data. If the data returned by the JsonNet data mapper does not validate against the Identity Schema of your project, the user will be redirected to the registration page where they need to update the missing fields. The data provided by the user and the data coming from the OpenID Connect / OAuth2 provider will then be merged. This process repeats itself until the Identity's traits are valid against the defined JSON Schema [[source](https://www.ory.sh/docs/kratos/social-signin/data-mapping#fill-in-the-data-gaps)]. If you're encountering common problems such as Redirect URI mismatch, Redirect loops during registration, or Domain verification issues, you can refer to the Social sign-in troubleshooting guide [[source](https://www.ory.sh/docs/kratos/social-signin/ory#troubleshooting)]. For more specific issues or detailed debugging, you might want to reach out to the Ory community or support for more assistance.
