Original GitHub issue: https://github.com/adamwalach/openvpn-web-ui/issues/26

How can I solve this error?
Environment
Platform: Raspberry Pi 3 B +
OS: linux
Architecture: arm
The source was compiled on the Raspberry Pi.

Action: Update the configuration of the default profile
Initially I had to comment on that configuration in the code because it gave me the same error.

@d3vilh commented on GitHub (Oct 1, 2021):

have kind the same issue on RPI 4b:

ebat@netm:~/tempo $ cat /etc/debian_version
10.10
ebat@netm:~/tempo $ uname -a
Linux netm 5.10.60-v7l+ #1449 SMP Wed Aug 25 15:00:44 BST 2021 armv7l GNU/Linux

Managed to build everything for arm v71, but it can't run properly.
DB seems on the place, instances and users were created, but it throws following, when I run it:

2021/10/01 12:12:56 [D] [models.go:88] {1 default openvpn:2080 tcp /etc/openvpn/ 127.0.0.1 2021-10-01 09:26:49.944566004 +0000 UTC 2021-10-01 09:26:49.944570911 +0000 UTC}

panic: reflect: call of reflect.Value.Int on string Value

goroutine 1 [running]:
reflect.Value.Int(...)
	/usr/local/go/src/reflect/value.go:1334

Update:
As a WA you can disable default profile configuration submit to o_v_config table by commenting out createDefaultOVConfig() function as part of init() in models.go:

func init() {
	initDB()
	createDefaultUsers()
	createDefaultSettings()
//	createDefaultOVConfig()
}

This will skip createDefaultOVConfig and web server starts normally.
