App manifest runtime behind (LC0033)
The runtime version specified in app.json should be kept up to date with the target Business Central version. Using an outdated runtime version may prevent you from using newer AL language features and APIs.
Example
If your app.json specifies an old runtime:
{
"runtime": "10.0"
}
And you’re targeting a newer Business Central version, update the runtime to match:
{
"runtime": "14.0"
}
