When publishing a Flow, you may encounter the following error:

Publishing Flow without data_channel_uri

You need to set the "data_channel_uri" property before you can send or publish a Flow. This error occurs when the required data_channel_uri property is missing from your Flow JSON. The data_channel_uri is essential for directing data to the appropriate endpoint, making it a mandatory field for publishing.

How to Fix the Error

Step 1: Check Your Flow JSON

Before publishing, verify that your Flow JSON contains the data_channel_uri property.

Step 2: Add the data_channel_uri Property

Modify your Flow JSON to include the missing data_channel_uri field. Here’s an example of the correct format:

Incorrect JSON (Missing data_channel_uri):

{
    "version": "2.5",
    "name": "Sample Flow"
}

Correct JSON (With data_channel_uri):

{
    "version": "2.5",
    "name": "Sample Flow",
    "data_channel_uri": "https://api.example.com/webhook"
}

Step 3: Save and Publish the Flow

  • After adding the data_channel_uri, save the Flow.

  • Validate the Flow using the Flow Builder UI or the API.

  • Once validation passes, proceed with publishing.
