On December 4, a Singapore Airlines Airbus A350-900 was operating flight SQ422, from Singapore to Mumbai, when it was forced to execute a go-around. The aircraft, registered 9V-SMH, eventually landed safely at Mumbai's Chhatrapati Shivaji International Airport at 10:44 AM local time.
Go-arounds are fairly common for commercial aircraft, and are commonly known as "missed approaches." These are often executed when an aircraft is trying to land in unsafe conditions, resulting in a procedure that involves climbing to a set altitude and making a "U-turn" to line up with the runway again.
News outlets originally reported that SQ422 had been attempting to land at Juhu Airport's runway 08, instead of Chhatrapati Shivaji International Airport's runway 09. They also reported that the Singapore Airlines pilots had accidentally attempted to approach the wrong airport. However, this is not true at all.
Looking at the aircraft's radar track, it was initially approaching Chhatrapati Shivaji International Airport from the west, when it was forced to abandon its approach due to unsafe weather conditions (i.e. low visibility), according to a statement from Singapore Airlines. As Juhu airport is located directly to the west of Chhatrapati Shivaji International Airport, it is plausible that journalists could have mistaken the missed approach for an attempted landing at Juhu. The aircraft circled around the area before performing a successful attempted landing attempt at 10:44 local time.

Here's the METAR Weather data for Mumbai, as provided by The Aviation Herald. It shows that there were poor visibility conditions during the time the Singapore A350 was landing. According to this report, the weather seemed to have been smoky, with low-level clouds at 2000 feet. These conditions don't seem too bad at first glance, but it's entirely possible that something could have moved into the area within a short amount of time as the A350 was preparing to land.
