val.foreach is not a function after it reaches the key.length 2 digits – Jquery ajax

I am making a matchmaking system where players with less than or greater than equal 15 weight, will be matched.

For example Player 105 has 2185 and player 132 has 2000. They'll be matched.

This is my example data from console log when they’re matched.

2185_2200: Array(2)
0: {entryID: '105', eventID: '22', …}
1: {entryID: '132', eventID: '22',  …}
length: 2

Now, my problem is i have also a no match players, and they’re displayed like this:

Is there a way where i can console.log only those data with ARRAY(2)? and ignore those players without a match?

My foreach doesn’t do an error when my no-matched players are only 9, but when it reaches 10, I’m getting an val.Foreach is not a function. I think I am missing another condition in my script. I hope you can help me, I’m stucked here for days. Thank you in advance and appreciate you

html:

//I am appending my result here
  <div id="resulta">
             
</div>

SCRIPT:

function newCombine(data, difference) {

  let nonMatched = [...data]
  const groups = {}

  for (let i = 0; i < nonMatched.length - 1; i++) {
    const first = nonMatched[i]

    inner: for (let j = nonMatched.length - 1; j > i; j--) {
      const second = nonMatched[j]
      const delta = Math.abs(first.weight - second.weight)

      if (delta <= difference && first.entryName !== second.entryName) {
        const groupKey = `${first.weight}_${second.weight}`
        groups[groupKey] = [first, second]
        nonMatched = nonMatched.filter(
          obj => obj.entryID != first.entryID && obj.entryID != second.entryID
        )
        i = -1
        break inner
      }
    }
  }
  return { ...groups, ...nonMatched }
