Create timebased trigger in side a for loop (apps script)

In an apps script project, i have to run a task that will take about 2 hours to complete,
so i decided to break it in parts and run each via timebased trigger.
In the below snippet:
the function longAction represent the function that needs to be run multiple times and this function will accept arguments a and b.

the lowerUpper() function returns a list of ranges[0-4, 5-9, 10-14, 15-19, 20-20], these represent row numbers in a googlesheet.

I tried creating copies of the longAction function using the bind method.
Which in turn i want to use in the ScriptApp timebased c while creating trigger.

Result: The triggers are created (ok).
Problem: I have the following error

Script function not found: function () { [native code] }

How can i correct the error? Or any other way of dealing with the problem.

I expected to create timebased triggers where each trigger runs the same function but with a different set of argument.

I have the following error:
Script function not found: function () { [native code] }

let longAction = function (a,b){
    for(let i =a ; i<= b ; i++){
        Logger.log(i) // for testing purpose
    }
 }

function test(){
    let rng = lowerUpper(20,4) // [0-4, 5-9, 10-14, 15-19, 20-20]

    for (j = 0; j < rng.length ; j++){
        let low = rng[j].split('-')[0]
        let upper = rng[j].split('-')[1]
 
    // create copies of longAction function to    use later in the trigger
        let action1 = longAction.bind(null,low,upper) 

       ScriptApp.newTrigger(action1)
       .timeBased()
       .after(1 * 60 * 1000)
       .create()
    }
}
