get_charts is having KeyError

[ankydv]

[1.2.1/1.1.1] get_charts is having KeyError: -

To Reproduce
Steps to reproduce the behavior:

1. Comment this section in explore.py since it's having KeyError, I'm unable to figure out.. Hence to avoid this error:-

charts['countries']['options'] = list(
             filter(None, [
                 nav(m, ['payload', 'musicFormBooleanChoice', 'opaqueToken'], True)
                 for m in nav(response, FRAMEWORK_MUTATIONS)
             ]))

1. Call the get_charts function (auth or without auth).

Additional context
With some analysis I've figured out that youtube returns different response for different videos.
It appears to only occurs in 'videos' section. Not 'trending'.

**Cause
The NAVIGATION_VIDEO_ID in navigation.py is not sufficient to cover all types of responses from Youtube as the reponse of Youtube is inconsistent.

Expected structure of response:-

'navigationEndpoint':  {
					"clickTrackingParams": "CL0JEKCzAhgAIhMImaOrk6rAgQMVq8JzAR3dbAig",
					"watchEndpoint": {
						"videoId": "RLzC55ai0eo",
						"playlistId": "PL4fGSI1pDJn40WjZ6utkIuj2rNg-7iGsq",
						"loggingContext": {
							"vssLoggingContext": {
								"serializedContextData": "GiJQTDRmR1NJMXBESm40MFdqWjZ1dGtJdWoyck5nLTdpR3Nx"
							}
						},
						"watchEndpointMusicSupportedConfigs": {
							"watchEndpointMusicConfig": {
								"musicVideoType": "MUSIC_VIDEO_TYPE_OMV"
							}
						}
					}

In some cases, the response is like: -

'navigationEndpoint': {
					"clickTrackingParams": "CLEJEKCzAhgBIhMImaOrk6rAgQMVq8JzAR3dbAig",
					"browseEndpoint": {
						"browseId": "MPEDVAdGW7QDJiU",
						"params": "ggMnmgEkCiJQTDRmR1NJMXBESm40MFdqWjZ1dGtJdWoyck5nLTdpR3Nx",
						"browseEndpointContextSupportedConfigs": {
							"browseEndpointContextMusicConfig": {
								"pageType": "MUSIC_PAGE_TYPE_NON_MUSIC_AUDIO_TRACK_PAGE"
							}
						}
					}
				}


				}

Possible solution

In those cases, the video ID exists somewhere else, not in 'navigationEndpoint', the navigation should be like: -
NAVIGATION_VIDEO_ID_2 = ['menu','menuRenderer','items',0,'menuServiceItemRenderer','serviceEndpoint','queueAddEndpoint','queueTarget','videoId']

Hence we could fix it by excepting the KeyError with this nav instead.

Which region are you looking at? Please specify the failing call in more detail. If it's the default region for you please figure out which one that is.

[ankydv]

I checked for default region as well as my region ('IN"). In both the cases there was the same issue. You could look the 'Error.txt' file that I have already dropped.

I am also facing the same issue,
for "ZZ" region as well as for "IN" region its giving keyError.
