Asus AC87U Advanced Wireless WebUI bug

[Dmytro]

Hello. I have Asus RT-AC87U with installed 384.13_10 merlin firmware

when I try to go to Wireless section in the left menu I get errors in console which prevents page to work normally
The error:

Uncaught SyntaxError: Unexpected end of JSON input
at JSON.parse (<anonymous>)
at chanspec.js:25

The problem:

if(based_modelid == "RT-AC87U"){
ch80m = JSON.parse(''); #<---- here should be JSON.parse('{}')
wl1.channel_80m.push("0");
for(i=0;i<ch80m.length;i++){
wl1.channel_80m.push(ch80m[i] + "/80");
}
ch40m = JSON.parse(''); #<---- here should be JSON.parse('{}')
wl1.channel_40m.push("0");
for(i=0;i<ch40m.length;i++){
wl1.channel_40m.push(wlextchannel_fourty(ch40m[i]));
}
}

please fix. Thank you in advance

What browser is that with? Have you tried any troubleshooting? What steps, if any?

Does clearing the cache work? Rebooting the computer, router, or both?

It must be something with your browser? Mine works as it should, no errors in display.

First browser was chrome latest
Tried to clear cache, tried with dev tools 'Disable cache'

Than I tried to change browser to fresh installed Firefox latest - the same.
Than I debugged the source code

As I've mentioned earlier the problem is in JS file. JSON.parse('') is a bug because json can't be empty. it must consists at least with '{}'

Is your 5GHz actually broadcasting and working?

no. 5ghz is not working
reverted to *_8 version and everything is ok.
