I'm trying to create an instance template using f1-micro, with all the default except service account. Using the one I created, with my custom vpc and custom role.

Creating instance template "frontend-it" failed. Error: Invalid JSON payload received. Unknown name "enableFlowLogs" at

What can could it be ?

Best regards people.

  • Show you code and the payload that generated this error. – John Hanley Jan 04 '21 at 21:30
  • Did you [followed](https://cloud.google.com/compute/docs/instance-templates/create-instance-templates) this document? – Mahboob Jan 04 '21 at 22:21
  • I've met the same issue. Someone has reported this issue to google support: https://issuetracker.google.com/u/1/issues/177345645 There's no more error when I retried it today. It seems resolved. – MQQ Jan 16 '21 at 13:51

Work around just in case anyone is interested

  1. select the source template
  2. create similar
  3. add/modify/change the new template according to requirements
  4. instead of clicking create at the bottom of the page, click on "command line"
  5. RUN IN CLOUDSHELL and execute and authorize the command

I had the same issue and followed Narender Gakka's workaround and still got an error.

Looks like the a flag was removed from templates. Older templates may include this flag but creating similar trys to add this deprecated(?) flag.

ERROR: (gcloud.beta.compute.instance-templates.create-with-container) unrecognized arguments: --reservation-affinity=any

I also encountered this issue that failed to copy instance template for all of my custom vpcs. It can be created by changing to default vpc. My solution is to

  1. Add a new subnet VPC Networks => MyVPC => Subnets => Add subnet => asia-east1-subnet2
  2. Copy an existing instance template
  3. Expand Management, security, disks, networking, sole tenancy => Networking => Subnet change to the subnet you just created and then change back to your original subnet
  4. then you can press Create
