Slack webhook to allow sending empty string

I'm implementing the Slack Incoming Webhook into my application but it seems to crash if values are empty. Does slack allow empty strings to be passed?

{
type: "plain_text",
text: req.body.contactNumber,
emoji: true,
},

So for example, the contact number won't always have a value inside the string. What's the best way to allow the message to be sent even if it is empty?

Solution

  • You could add a default value in case there is none:

    {
  type: "plain_text",
  text: req.body.contactNumber || 'none',
  emoji: true,
},
