The syntax seems fine as far as the commands are concerned.

Is it possible that there is a problem with the contents of the configuration file?
It didn't work. I want to just change the instance type. Could you please guide me how to do it? Without pcluster update?
Hi!
The file in the parallelcluster-224514400f379bb5-v1-do-not-delete/parallelcluster/3.6.0/clusters/hpc-fz9dgvd5ws1q29hz bucket is required, because the CLI will use it to compare new cluster configuration with previous configuration.
Is your cluster hpc-fz9dgvd5ws1q29hz created with version 3.6.0 of ParallelCluster?
The cli is able to retrieve the previous configuration file unless it has been manually deleted. Can you check the bucket existence?

Hi, There is no problem with the configuration file because I am working on my HPC and also, I have that exact same file on my local machine. Could be because the default location of the config.yaml is in that path. What do you think? How can I change that default location?
I didn't think the location of the files was that important. What happens if I specify a file by absolute path as follows?
Looking at the following document, I thought that "InstanceType" could not be changed in the configuration file. https://docs.aws.amazon.com/parallelcluster/latest/ug/HeadNode-v3.html#yaml-HeadNode-InstanceType
If it was a head node instance type, I believe it could be changed from the management console.
