Crash when trying to debug: "no entry found for key"

Summary

If I have try to debug after having set a breakpoint helix crashes with the following error. The code is using async I don't know if that matters

RUST_BACKTRACE=full hx -vv .

This is my configuration (I mainly copied it from the default):

[[language]]
name = "rust"
auto-format = true

[language.debugger]
name = "lldb-dap"
transport = "stdio"
command = "lldb-dap"

[[language.debugger.templates]]
name = "binary"
request = "launch"
completion = [ { name = "binary", completion = "filename" } ]
args = { program = "{0}" }

[[language.debugger.templates]]
name = "binary (terminal)"
request = "launch"
completion = [ { name = "binary", completion = "filename" } ]
args = { program = "{0}", runInTerminal = true }

[[language.debugger.templates]]
name = "attach"
request = "attach"
completion = [ "pid" ]
args = { pid = "{0}" }

[[language.debugger.templates]]
name = "gdbserver attach"
request = "attach"
completion = [ { name = "lldb connect url", default = "connect://localhost:3333" }, { name = "file", completion = "filename" }, "pid" ]
args = { attachCommands = [ "platform select remote-gdb-server", "platform connect {0}", "file {1}", "attach {2}" ] }

Reproduction Steps

I tried this:

hx
Open a test file
Set a break point
Run the debugger choosing a the binary

I expected this to happen: The debugger runs and stops at the breakpoint

Instead, this happened: A crash

I ran RUST_BACKTRACE=full hx -v
