# All the DX!

## Ask AI

Ask AI for help from the [docs](https://www.tinybird.co/docs/forward/quickstarts) or [community Slack](/community).

## Create blank Data Sources in the UI

Create blank Data Sources in the UI without sending any data or using the CLI.

Add a new Data Source using the normal UI flow and select the 'Write schema' option. You can write the schema manually in the text editor modal that appears.

## Update your Kafka Connector settings in the UI

Update the settings for an existing Kafka connection without leaving the UI.

Open the list of Kafka connections, select the 3-dot menu for the connection you want to update, and select 'Edit settings'. You can update the connection name, Kafka brokers, auth creds, SASL mech and schema registry settings.

## Error logging for BigQuery & Snowflake Connectors

Use the `datasources_ops_log` to see find errors for any BiqQuery or Snowflake jobs that go wrong.

You can query the `datasources_ops_log` log like any other Service Data Source to find information about your Tinybird usage. The `datasources_ops_log` will now include detailed error messages for any BigQuery or Snowflake jobs that fail.

## See when your Materialized Views have errors

If a Materialized View has an error, you'll see a red dot next to it in the sidebar.

If you see a red dot next to a Materialized View in the sidebar, select the MV to see more details about the error. To dismiss the notice, open the MV and select the 'Dismiss' button.

## Multiple Auth Tokens in .datasource files

Use multiple `TOKEN` lines at the top of a .datasource file to create multiple Auth Tokens.

Previously, you could only use one `TOKEN` line at the top of a .datasource file to set the Auth Token. You can now add as many `TOKEN` lines as you need to create multiple Auth Tokens.

## Other notable changes

- Better Kafka Connector error messages
- Fixed various formatting errors when displaying data in the UI
- Show external ID in the S3 Connector CLI output
