Issue while setting up plugin development environment

I am trying to setup the plugin development environment in Ubuntu 20.04 LTS (64 Bit)

I have followed the steps as per the instructions from the official tutorial

But, I am getting warning in ‘yarn install’ step and getting error in ‘yarn dev’ step

:heavy_multiplication_x: Failed to load config “prettier” to extend from.
Referenced from: ~/src/grafana-plugins/my-plugin/.yarn/$$virtual/eslint-plugin-prettier-virtual-afd8534cb2/0/cache/eslint-plugin-prettier-npm-3.1.4-eba11cd45a-4e4df15579.zip/node_modules/eslint-plugin-prettier/eslint-plugin-prettier.js

How can this be solved?
