iDRAC8 redfish_idrac_firmware R730

Hi Dell

We are trying to update iDRAC8 firmware from 2.60.60.60 to 2.70.70.70.
Using the Ansible module redfish_idrac_firmware from dellemc-openmanage-2.1.1

I have used the .d7 name as well as one used for iDRAC9 (.d9) that works fine.
IDRAC_2.75.75.75.d7

The message is:

"changed": false,
"invocation": {
"module_args": {
"baseuri": "ltapp201k",
"image_uri": "/global/instserv/packages/firmware/iDRAC_2.70.70.70_A00.exe",
"password": "VALUE_SPECIFIED_IN_NO_LOG_PARAMETER",
"transfer_protocol": "HTTP",
"username": "Administrator"
}
},
"msg": "Target firmware version doesn't support HTTP protocol."

Same message with /global/instserv/packages/firmware/IDRAC_2.70.70.70_A00.d7

If you could help please?

Regards,
Jan
