How to override an ARMTemplateParametersForFactory.json [Array as value]

[Chatop0Z]

I already got help from this
"You can override the parameters in parameter file by explictly calling it out next to the parameter file.
Example :
parameters: repo/ARM/azuredeploy.resourcegroup.parameters.json rgName=${{env.RESOURCEGROUP_NAME}}
This will override the rgName."

But the problem I got for now is I have Key, Values as this in ARMTemplateParametersForFactory.json

  "parameters": {
	"factoryName": {
		"value": "adf-dev-pep"
	},
	"mpep-sta_properties_fqdns": {
		"value": [
			"stadevpep.dfs.core.windows.net"
		]
	},
}

I already override factoryName as this in GitHub Actions

parameters: ./ARM/ARMTemplateParametersForFactory.json
factoryName=adf-prod-pep
mpep-sta_properties_fqdns=[stadevpep.dfs.core.windows.net]

The error said:

Validating template...
Warning: ERROR: Failed to parse string as JSON:
[stadevpep.dfs.core.windows.net]
Error detail: Expecting value: line 1 column 2 (char 1)

Warning: Template validation failed.
Creating deployment...
Error: ERROR: Failed to parse string as JSON:
[stadevpep.dfs.core.windows.net]
Error detail: Expecting value: line 1 column 2 (char 1)

How should I override the Array value in this case
