Solution
    • This might be the known bug in the azure function extension bundle. So a work around for that, in your project remove the following code from the host.json file
    "extensionBundle": {

"id": "Microsoft.Azure.Functions.ExtensionBundle",

"version": "[3.*, 4.0.0)"

}

    enter image description here

    • Then restart the project with the following command
     mvn -e  azure-functions:run

    enter image description here

    Refer the work around given in this question
