HI Himanshu, Based on the error,it looks like the project is not set up correctly or the sfdx-project.json file is missing from the root directory of the project.
Try these steps: >Open Visual Studio Code. >Click on the Explorer icon at the top left of the screen. >Click on the Open Folder button. >In the window that pops up, find the folder that contains your Salesforce DX project. >Click the Open button to continue. If the sfdx-project.json file is missing, you can create it by running " sfdx force:project:create -n yourprojectname "
Once you have the sfdx-project.json file in the root directory of your project, you should be able to open it in Visual Studio Code without encountering the error message.
