Error : transaction underpriced

[Aishwaria8786]

I am facing this following problem.

Let's deploy with only transacton data!
Error: could not coalesce error (error={ "code": -32003, "message": "transaction underpriced", "stack": "Error: transaction underpriced\n    at shouldReplace (C:\\Program Files\\WindowsApps\\GanacheUI_2.7.0.0_x64__rb4352f0jd4m2\\app\\resources\\static\\node\\node_modules\\ganache\\dist\\node\\1.js:2:119740)\n    at TransactionPool.prepareTransaction (C:\\Program Files\\WindowsApps\\GanacheUI_2.7.0.0_x64__rb4352f0jd4m2\\app\\resources\\static\\node\\node_modules\\ganache\\dist\\node\\1.js:2:122311)" }, code=UNKNOWN_ERROR, version=6.2.3)

    code: -32003
  }
}

What should I do?

@Aishwaria8786 Can you give some context, which lesson you are working on, and what you did when this error occurs? link to repo etc.

It was in lesson 5.deploy.js file.
