MakeCode fails to compile extension

[microbit-carlos]

After a while compiling it shows the following error:

The hex file is not available, please connect to internet and try again.

And the js console prints:

Looks like maybe it's failing to compile for V1.

Workaround

Disable building for V1 by adding this to pxt.json:

{
    "disablesVariants": [
        "mbdal"
    ]
}

For example, at the end of the file:

Update in v0.1.1

This should not longer be a problem with the latest version of the extension.
