wtp-mode is read only when creating / modifying fortios_wirelesscontroller_wtp

[rfranks-securenet]

When creating a WTP with the resource fortios_wirelesscontroller_wtp, and specifying the wtp_mode as remote, I get an error.

Once I have created it, leaving out the wtp_mode parameter, if I try to reapply, I get the same error, and this time have to put in wtp_mode to remote to match the setting on the FortiGate itself

On first creation:

Not working

resource fortios_wirelesscontroller_wtp ap {
  wtp_id                                = "<serial_number>"
  name                                  = "test-ap"
  wtp_mode                              = "remote"
  wtp_profile                           = "myProfile"
}

  wtp_profile                           = "myProfile"
}

On update

Not working

Hi @rfranks-securenet ,

Sorry for the late reply and thanks for reporting this issue.

Could you please help to provide:
The exact FortiGate firmware version you are using (e.g., 7.6.x / 7.4.x build number).
If possible, please also provide the CLI configuration output or commands you executed on the FortiGate when the error occurred.

Please feel free to mask or remove any sensitive information (IP addresses, serial numbers, domain names, etc.).

Thank you!

Thanks, Douglas,

The FortiOS version is 7.4.9 build 2829.

I don't do any CLI configuration on the fortigate. As I say, the first time I apply the configuration it doesn't accept the wtp_mode option, and applies correctly. On subsequent runs, it does not apply unless I specify the wtp_mode.

Thanks,
Richard
