Go YAML Conversion Error: How to Fix 'runtime error: assignment to entry in nil map'?

Runtime Error: Assignment to Entry in Nil Map

In your Go program, you encountered a runtime error while attempting to create a map and convert it to YAML. The error message "runtime error: assignment to entry in nil map" indicates that you attempted to assign a value to a nil map key.

To resolve this issue, ensure that you properly initialize your nested map. Before the start of your for loop, add the following line:

m["uid"] = make(map[string]T)

This line creates an empty map under the key "uid" in the outer map m. You can then modify your for loop to assign values to the nested map:

for _, name := range names {

    t := T{cn: "Chaithra", street: "fkmp"}

    m["uid"][name] = t

}

By initializing the inner map before assigning values, you avoid the runtime error and allow for successful map population. The updated code should now produce the desired output.
