"sshkeys":"invalid format - invalid urlencoded string

[LexyJexon]

Hello everyone! I'm trying to set template's cloud-init configs via proxmox-api-go package's proxmox.Client.SetVmConfig() method. I need to set username, password, ssh-key and network configs. I created variable map[string]interface{} with content:
{
"ipconfig0": NewNet0Cfg,
"ciuser": username,
"cipassword": password,
"sshkeys": encodedKey,
}

all these keys's values hane type string
I have problem only whith sshkey. First I created variable SshKey := "ssh-rsa AAAAB3...."
Then I tried to urlencode it wirh net/url package :
encodedKey := url.QueryEscape(SshKey)
But when I call SetVmConfig() method I get this responce:

HTTP/1.1 400 Parameter verification failed.

Can you help me solve this problem please?

seems like you have a newline (\n) at the end of your sshkeys string, which seems to be the problem since \ is not valid in an urlencoded string - you should probably remove it completely

Thanks for your reply, I tried to remove \n from the end of string with my ssh key with strings.TrimRight(encodedKey, "\n") But problem still exists.
In request there is no \n:

I think it appears only in response output, and problem in anything alse, I still need help.

I too was having this problem when using go's url.QueryEscape() function to encode an ssh key. The problem is that spaces are encoded as "+" so to get around this you can do something like the following:

strings.Replace(url.QueryEscape(sshKey), "+", "%20", 1)

I get virtually the same error when sending an sshkey via URI in Ansible. There is no \n or "+" in the variable after {{ | urlencode }}.
But in the error message, as in the error output above, a \n is appended to the string.
How can I fix the error at all? Thanks for any help!

Ansible task:
- name: configure vm
uri:
url: "https://{{ server_url }}:8006/api2/json/nodes/{{ node }}/qemu/{{ vmid_next | trim }}/config"
method: POST
return_content: yes
body_format: json
use_proxy: no
validate_certs: no
timeout: 5
headers:
Authorization: "PVEAPIToken=..."
Content-Type: "application/json"
body:
vmid: "{{ vmid_next | trim }}"
[...]
ciuser: "{{ inventory_settings__pve_vm_username }}"
sshkeys: "{{ inventory_settings__pve_vm_public_key | trim | urlencode }}"
[...]

Stefan, can you check my issue (same with "\n") one line above (Monday) ? Thanks!

I know its been a while since you posted this but I wanted to provide some help for those who have been bashing their brain on this issue like myself for way too long.

This worked for me so far. I dont like it and I dont agree with it at all.

vm_sshkeys is a fact that I have that contains my public ssh key in a string format. I run this step before calling the URI and using encoded_sshkeys_output to populate the sshkeys property.

- name: Encode SSH Keys for Proxmox
  ansible.builtin.shell: |
    python3 -c "import urllib.parse, sys; print(urllib.parse.quote(sys.argv[1], safe=''))" "{{ vm_sshkeys }}"
  register: encoded_sshkeys_output
  changed_when: false

FYI, I created an account on this forum just to respond to this for any future head bashers out there.
