Create Thing kotlin NotAuthorizedException.

[mbahmani90]

Hi,

Hope you are all well.

I want to create thing via android kotlin.

Kotlin Code:

    fun initAWSIotClient(context: Context) {
        val credentialsProvider = CognitoCachingCredentialsProvider(
            context,
            "MY_USER_POOL_ID",
            MY_REGION 
        )
        iotClient = AWSIotClient(credentialsProvider)

        createThing("MyNewThing")
    }

    private fun createThing(thingName: String) {
        Thread {
            try {
                val createThingRequest = CreateThingRequest()
                createThingRequest.thingName = thingName

                val createThingResult = iotClient.createThing(createThingRequest)
                app.l("Thing created: ${createThingResult.thingName}")
            } catch (e: Exception) {
                app.l("Error creating thing: $e")
            }

        }.start()
    }

However, I receive error:

Failure to get credentials

com.amazonaws.services.cognitoidentity.model.NotAuthorizedException: Unauthenticated access is not supported for this identity pool. (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: NotAuthorizedException; Request ID: xxxxx)

I also added different permissions to the IAM role like AWSIoTFullAccess, AWSIoTThingsRegistration, and test custom policy:

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Effect": "Allow",
			"Action": [
				"iot:CreateThing",
				"iot:DescribeThing",
				"iot:DeleteThing"
			],
			"Resource": "*"
		}
	]
}

but the error persists. Do you know how I should solve the error?

Thank you.
