Arm template with a parameter of array type is resulting in an exception when deployed

[ashwinvenkatesha]

Describe the bug
Arm template with a parameter of array type is resulting in an exception when deployed

To Reproduce
Steps to reproduce the behavior:

1. When deploying data connector using arm template and createUidefn,
   use
   a. https://github.com/illumio-shield/Azure-Sentinel/blob/illumio-sentinel-array-bug/Solutions/IllumioSaaS/Data%20Connectors/azuredeploy_IllumioSaaS_FunctionApp.json#L94-L96 for arm template
   b. https://github.com/illumio-shield/Azure-Sentinel/blob/illumio-sentinel-array-bug/Solutions/IllumioSaaS/Data%20Connectors/createUiDefinition.json for createUidefn](https://github.com/illumio-shield/Azure-Sentinel/blob/illumio-sentinel-array-bug/Solutions/IllumioSaaS/Data%20Connectors/createUiDefinition.json#L207-L250

c. Deploy this using the below command
https://portal.azure.com/#create/Microsoft.Template/uri/https%3A%2F%2Fraw.githubusercontent.com%2Fillumio-shield%2FAzure-Sentinel%2Fillumio-sentinel-array-bug%2FSolutions%2FIllumioSaaS%2FData%2520Connectors%2Fazuredeploy_IllumioSaaS_FunctionApp.json/createUIDefinitionUri/https%3A%2F%2Fraw.githubusercontent.com%2Fillumio-shield%2FAzure-Sentinel%2Fillumio-sentinel-array-bug%2FSolutions%2FIllumioSaaS%2FData%2520Connectors%2FcreateUiDefinition.json

2. This results in an internal server error.

There was an unexpected InternalServerError. Please try again later. x-ms-correlation-request-id: 44901431-c2d9-46b8-a17a-3782c1498d38 (Code: InternalServerError)

Upon removing this section

"parameters": { ... "networkTrafficLogTypes":{ "type": "array" }, ...
the deployment works as expected.

Expected behavior
Using array datatype should not result in an internal server error.

@ashwinvenkatesha , Can you check with Type : string:

try to deploy in different workspace to avoid resource duplication issue.
