ARM Template error error code invalidTemplate "Circular Dependancy Detected - azure-resource-manager

Question

I am new to deploying ARM templates. Before I created the ARM template I created a simple infrastructure consisting of 1 VM, 1 VNet, and 1 storage account. Once I finished provisioning the infrastructure, I decided to make a template for future use. I went under automation scripts, and I saved it to the library and then I also downloaded it. So, I wanted to change the SSD disk tier in the template from Standard D2S_V1 to E2S_V3. So I did that. I saved the changes and then I decided to test it out by deploying the template. After this, I got an error code that says the following:
Deployment template validation failed: 'Circular dependency detected on resource: '/subscriptions/7b790d29-944d-4f0f-861b-928e4774cde9/resourceGroups/SimpleRev2/providers/Microsoft.Network/networkInterfaces/simplevm18'. Please see https://aka.ms/arm-template/#resources for usage details.'. (Code: InvalidTemplate)
So, I tried to do my own research by checking out these links:
https://social.msdn.microsoft.com/Forums/en-US/c5782362-3a04-47fe-b5ec-87e5f488e844/deployment-failed-with-arm-template?forum=WAVirtualMachinesforWindows
https://learn.microsoft.com/en-us/azure/azure-resource-manager/resource-group-define-dependencies
I understand that the circular dependency error means that the dependOn property may be having issues. So I went in the template and looked at them, because it mainly has to do with the vnet resources specified in the template. What I'm not sure is, do I need to change the name of the vnet, pub ip, nsg, and nic? Or, is it something else. Here I'm going to attach the template in JSON:

Answer 1

the template is pretty big, i wont be able to look at it. but the error means that you have a dependency loop in your template. you need to analyze dependsOn and reference() in the template to detect it.
because both of these act as a dependency "marker"
