Visual Studio debugging "Failed to decrypt settings. Encrypted settings only be edited through 'func settings add'".

[grahambunce]

Create an Azure Functions 2.x C# app and associated function Add local.settings.json, e.g.

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "WEBSITE_MAX_DYNAMIC_APPLICATION_SCALE_OUT": "1"
  },
  "AppSettings": {
    "local.logging.path": "c:\\temp\\diagnostics\\",
  },
  "ConnectionStrings": {
    "management.webhook": "http://localhost:35617",
    "management.circuitbreaker.timespanSeconds": 60
  }
}

Note that the connection string contains an unexpected value ("management.circuitbreaker.timespanSeconds")

Execute similar layout in WebJobs SDK = no issues Execute layout in Azure Functions = fail on startup with "Failed to decrypt settings. Encrypted settings only be edited through 'func settings add'."

Error is incorrect and misleading; nothing to do with encryption (as local.settings.json has "IsEncrypted": false) but is in fact due to a failure to parse the "management.circuitbreaker.timespanSeconds": 60 value.

Expected that the error does not refer to encryption but instead refers to "cannot parse settings file" and preferably with the value that is causing the problem,

Seeing this as well when trying to create launch this repo in a GitHub codespace.

Dialog in VsCode:

And the terminal output:

Function Runtime Version: 3.0.14916.0

Failed to decrypt settings. Encrypted settings only be edited through 'func settings add'.
The terminal process "/bin/bash '-c', 'func host start'" terminated with exit code: 1.

I managed to encrypt by running 'func encrypt' But before doing this, you need to make sure IsEncripted is set to false. (I set this to true manually)
