GDScript completion does not insert anything in some scenarios

[rcorre]

Summary

Given the following script:

extends Spatial

func _ready():
	var data := var2bytes(self).compress(File.COM

Completions selected after COM will not insert anything.

Reproduction Steps

I tried this:

1. hx Example.gd
2. Move the cursor after "COM"
3. Press Tab a few times.

I expected this to happen:
Selected completions are inserted.

Instead, this happened:
Completions are selected but nothing is inserted.

I'm wondering if this could be a bug in Godot's LSP. In the case above, the response looks like:

{"data":"File::COMPRESSION_GZIP","insertText":"","kind":21,"label":"COMPRESSION_GZIP"}

However, if I type: var c := File.COM<TAB>, the response looks like:

{"data":{"position":{"character":15,"line":108},"textDocument":{"uri":"file:///home/rcorre/src/agos/singleton/SteamAPI.gd"}},"insertText":"COMPRESSION_ZSTD","kind":21,"label":"COMPRESSION_ZSTD"}```

I use GODOT 4.0.3.stable.official ,
helix (master > 23.05)

The LSP runs properly.

On godot 4.0.3.stable.arch_linux helix 23.03, I still see this behavior.

@erasin when you type TAB, does it actually insert COMPRESSION_FASTLZ? For me it just clears com.
