Broken flow.json when deploying contract with [String] as init arg

[sisyphusSmiling]

Problem

Whenever using CLI to deploy a contract with an array of String in init args - e.g. init(_ a: [String]) - deployment succeeds but the init args as defined in the flow.json break the config file.

Steps to Reproduce

Init project:

flow init

Add the contract

access(all) contract C {
    access(all) let arr: [String]
    init(arr: [String]) {
        self.arr = arr
    }
}

Run emulator and deploy the contract with

flow accounts add-contract ./contracts/C.cdc '["a", "b"]'

Try to run any other CLI command and get

❌ Config Error: failed to decode JSON-Cadence value: invalid type: [String]

Looking at the flow.json, we see

{
	"name": "C",
	"args": [
		{
			"type": "[String]",
			"value": "[a b]"
		}
	]
}

Which should be

{
	"name": "C",
	"args": [
		{
			"type": "Array",
			"value": [
				{
					"type": "String",
					"value": "a"
				},
				{
					"type": "String",
					"value": "b"
				}
			]
		}
	]
}
