Failed to enter configuration mode in Netmiko while trying to use send_config_set

I'm new to Python and Netmiko. I;m trying to use netmiko to login to aruba switches. while i pass on some commands using send_config_set, it is erroring out saying "failed to enter configuration mode" am i missing anything here.

one solution was suggested to set "fast_cli to False" and global delay factor to 4 and even that did not work.

can someone help me with this pls?

from netmiko import ConnectHandler
network_device = {"host": "x.x.x.x",
                  "username": "admin",
                  "password": "password$",
                  "device_type": "aruba_os"}

with ConnectHandler(**network_device) as ssh_connect:
    print(ssh_connect.find_prompt())

    for vlan in range(1001,2000):
        config_commands = ['Vlan ' + str(vlan), 'name: Private_Vlan ' + str(vlan)]
        output = ssh_connect.send_config_set(config_commands)
        print(output)

    raise ValueError("Failed to enter configuration mode.")
ValueError: Failed to enter configuration mode.

I tried to run netmiko debug and looks like netmiko is issuing the commands correctly. Netmiko logs are:

You can use the sample code I wrote below. It will be enough to update the prompt section.

try:
    network_device = {
        'device_type': 'aruba_os', 'ip': x.x.x.x, 'username':
            username, 'password': password, }
    net_connect = Netmiko(**network_device)
    print("success enter")
except Exception as e:
    print(e)
    return

prompt_aruba_fnk = net_connect.find_prompt()
hostname_fnk = prompt_aruba_fnk.strip("<" + ">")
print(hostname_fnk)
net_connect.send_command_timing("enable")
net_connect.send_command_timing("undo smart")
output = net_connect.send_command_timing("config")
print("entered config mode")
net_connect.send_command_timing("acl 2010 ")
net_connect.send_command_timing("save")

print("islem tamamlandi")
with open("MDU_OK_2.txt", "a") as f:
    f.write(nodeip + "\n")
    f.close()

net_connect.disconnect()
