nvim-cmp crash, error "'start' is higher than 'end' " on selecting copilot item

[Rhymond]

When I select a Copilot generated item, I encounter an error and nvim-cmp crashes with the error mentioned below. It looks like cmp tries to replace the entire line. However, I think that when my cursor is at the end of the line, it causes the cmp to crash and returns an error (this is just my wild guess).

Here is a video demonstrating the issue being replicated:

copilot settings

    require("copilot").setup({
        suggestion = { enabled = false },
        panel = { enabled = false },
    })

    require("copilot_cmp").setup()

I'm not sure if the issue lies with nvim-cmp or copilot-cmp package. However, I cannot reproduce the same error with other cmp selections.

[rsarv3006]

Running into this as well.

[sommerper]

I'm having the same issue, however, it's always on the third time I select something.

[zbirenbaum]

I haven't run into this, but I would guess it has to do with completion insert and replace ranges since I've seen similar errors when experimenting with those. Try out #92

[ivanlee1999]

Still encounter same issue
It happens every time when I try to edit fields of golang structs

[palcalde]

Same here, with golang structs.

[mahmoudk1000]

Running into this same problem.

[fira42073]

This crashes the nvim-cmp completely. It's a huge bummer in my workflow and I have no idea how to fix it (tried various options).

Same problem with golang structs.

[k1ng440]

I have the same problem.

Mostly happens in Golang.

[fira42073]

I wonder how it can be fixed. Any advice on where to look? I'd fix it myself, but I don't have a lot of experience with lua, except doing minor fixes in my own config.
Thanks in advance!

As a fairly reproducible example for me, create a file with the following Go code

package main

type Test struct {
	Name string `json:"name,omitempty"`
	Age  int    `json:"age"`
}

Go to Age field, and delete the backtick, there will be a suggestion to add the omitempty to the json definition.

Cmp will crash, and some wierdness goes on where the code is collapsed into one line

[tris203]

PR to CMP above that seems to fix this issue for me
