not able to genereate device_page.hex for mesh_dfu example

[nikunj8086]

hi,

i am doing nrf_mesh_dfu example with nrf_sdk_for_mesh v1.0.1.

so far i am able to generate device public_key and private key by following instructions.

and also generated dfu file. but when i added public key in "bootloader_config_default.json"  which is exacty like this.

{
    "bootloader_config": {
        "bootloader_id": 1,
        "bootloader_version": 1,
        "company_id": 89,
        "application_id": 1,
        "application_version": 1,
		"public_key": "34fdf55c448c77577f69e2969189d946cabf9aaefdce3cacf64e4dbd4d10781d67ccc090838cc43ea3c3e6f91c0646b538e33656733c98a80a7d1ea65697ec9e"
    }
}

for above json file i got error:

Traceback (most recent call last):
  File "device_page_generator.py", line 241, in <module>
    main()
  File "device_page_generator.py", line 235, in main
    write_specific_page(platforms, softdevices, args)
  File "device_page_generator.py", line 178, in write_specific_page
    device_page = DevicePage(platform, softdevice, bootloader_config)
  File "device_page_generator.py", line 94, in __init__
    self.generate_entries(platform, softdevice, bootloader_config)
  File "device_page_generator.py", line 103, in generate_entries
    DevicePageEntry(BLInfoType.ECDSA_PUBLIC_KEY, public_key))
  File "device_page_generator.py", line 69, in __init__
    raise TypeError
TypeError

but when i remove public key entry from json file it successfully creates device_page.hex

i also want to know that it is necessary to add public key in json file. if remove private key from dfu package.

please help me out.
