Crash caused by missing name on field definition #453
Description
New with the latest install of RPGLE while launching my RPGIV2FREE extension in debug mode this new error occurs where it looks like it dumped a ton of javascript to the Output window, I believe it was server.js But here's the start of what I saw:
"[Info - 9:12:08 AM] Connection to server got closed. Server will restart.
[Error - 9:12:08 AM] Request textDocument/codeAction failed.

==========
This is what GitHub CoPilot said about it:
the RPGLE language server crashing and auto-restarting. Not fatal, but it’s a real bug that can break code actions/symbols until fixed.
What the log means:
“Connection to server got closed. Server will restart.”: VS Code LSP client saw the server process die and restarted it.
“Connection got disposed.” on codeAction: a request hit during shutdown.
“documentSymbol failed … Cannot read properties of undefined (reading 'range')”: a null/undefined node without a position.range triggered an exception in the server.
The “ton of JavaScript” is the bundled, minified server restarting; “Debugger listening …” is Node’s inspector.
When to worry:
If it happens once, you can ignore. If it repeats, features like Outline, Go to Symbol, Code Actions will be flaky for that file.
Quick mitigations:
Reload Window (Cmd+Shift+P → Developer: Reload Window).
Update vscode-rpgle to the latest.
Try disabling it temporarily to confirm it’s the cause (Help → Start Extension Bisect).
If you want to chase it down:
It’s in the server’s documentSymbol path. Likely a symbol node missing position.range (your earlier structs/constants dump shows position.range present; a specific construct may be missing it).
In the repo, search for “documentSymbol” and inspect where it reads node.position.range; add guards or ensure every produced node has a range.
Enable verbose logs if supported (check extension settings for trace) or run the extension from source and set breakpoints around documentSymbol creation.
Workaround in your files:
If a specific member triggers it, isolate a minimal snippet and report it upstream. Ensuring every symbol you emit (constants, structs, subItems) has a valid position.range will avoid this exact error.
