Line Motion Invalid argument -1

[Nealium]

Using the (leader)j or (leader)k sometimes breaks. More than likely it's due to me upgrading to Vim 9.0, my odd tabbing of JQuery objects and the folding
I've provided a js file snippet at the bottom, from the last time I ran into the error, I just trimmed the fat a bit.

Recreating

• I've created a condensed js file, that's raising the error always after follow steps:

1. Fold line 19 ( :19 + za )
2. Goto Line 15 and hit (leader)j (:15 \j)

• it's not specifically on line 15, it's the area, but that's what I originally hit
• Note: \k works from this area, but sometimes it's flipped \k is broken and \j works

$(document).ready(function() {
  if (blah.exists){
    $('#submit').click(function(){
      $.ajax({
        method: 'post',
        url: '/form_submit’,
        data: {},
        success: function(data){
          if (data['status']){
            $('<tr></tr>')
              .append(
                $('<th></th>')
                  .append(
                    $('<input></input>')
                      .addClass('buglocation') // \j on this line
                  )
              )
              .append(
                $('<th></th>') // fold right here
                  .append(
                    $('<input></input>')
                  )
              )
          }
        }
      });
    };
  };
});

Folded = Broken

Unfolded = works

edit: fixed missing quote in code block

Update

On the example I gave if I tab over line 23 once, the issue doesn't happen- I knew it was my tabs :(

after tinkering: slightly editing it to double check that it's skipping lines that are inside folds, seems to fix the issue.

Original

• autoload/EasyMotion.vim around line ~1037

            if EasyMotion#helper#is_folded(pos[0])

I have recently started using EasyMotion, and I am experiencing the same issue, but with all commands. Whenever a fold exists in the forward search direction, EasyMotion fails with a message similar to that in the OP.

I am using freshly updated versions of vim (9.0.1302) and EasyMotion. Before I updated the errors occurred in both directions, but now it only happens with forward searches. Backward motions all seem to work fine.

The only changes I have made to the default configuration are setting use_upper and some color tweaks.

I can confirm that @Nealium 's edit works for me -
without the edit, I can't use f with many characters in a folded file. With it, no issue.

(Fresh install of easymotion today)

Thank you @Nealium .
