[BUG] Rancher provider injects whitespace into rke_config yaml which breaks the Rancher UI.

[st33v]

Rancher Server Setup

• Rancher version: v2.9.1
• Installation option (Docker install/Helm Chart): Not sure.
• Proxy/Cert Details: n/a

Information about the Cluster

• Kubernetes version: v1.30.6+rke2r1
• Cluster Type (Local/Downstream): Downstream

• Infrastructure Provider = vSphere

User Information

• What is the role of the user logged in? Admin

Provider Information

• What is the version of the Rancher v2 Terraform Provider in use? reproduced with v5.x and v6
• What is the version of Terraform in use? Terraform v1.0.11 on windows_amd64

Describe the bug

I'm using the rancher provider and adding a couple of add-on configuration options related to vSphere. The provider works fine, BUT when I look in the UI, I'm missing parts of my vSphere options...

When I view the YAML, I see that the values ARE there, but so is a single line of whitespace (line 314):

If I remove that whitespace, the UI displays my add-on config normally.

To Reproduce

Use the TF rpoivider to spin up a cluster with some vSphere add-on configs?

Actual Result

The TF provider pooped a blank line into my config and broke the UI.

Expected Result

I'd expect that the provider would clean up any undesirable characters before talking to the Rancher UI.

Screenshots

see above.

Additional context

nope.

Have you tried chomping the value in the Terraform config?

[st33v]

Yes, I've wrapped any yaml inputs into the provider in trimspace(yamlencode(<actual_config>)). SO... I'm not even using any heredoc strings in my input.... It's all HCL that's encoded to yaml and then has trimspace() run on it. I can't sanitize my input any more than that unless you think chomp() would do something different.
