Error: The terraform-provider-proxmox_v2.9.14.exe plugin crashed!

I get the same error, although the VM is created and i can manually start it up fine.

When i enable debug logging, it looks like the type error is in the response from proxmox, where the "memory" is is formatted as a string unlike e.g. "cores".

This is the my first time trying out both proxmox and terraform, so I might be wrong.

I had a try at it again, where i set up a proxy between terraform and proxmox, that changed the value of "memory" from string to integer for requests to the endpoint /nodes/proxmox/qemu/<vm_id>/config. And it worked!

This could easily be handled by the provider, but isn't this an error that should be fixed in Proxmox?

[Yfksw65]

Same problem for me, any fix please ?

[ksparwald]

Hi there,

Unfortunately the 2.x provider version is broken.
Please try the 3.0.1-rc6 version.
Also check the documentation because the schema has changed!

[Yfksw65]

Everything is fine in 3.0.1-rc6 thank you 👍
