[Bug]: runCurrentStatement fails with "Internal Parser Error" on macOS ARM64 - webview not initializing

[brian-aroflo]

Description

MSSQL Extension Version: 1.42.2

VS Code Version: 1.119.0 (Universal)

OS: macOS Darwin arm64 25.4.0 (Apple M5 Pro)

Steps to reproduce:

1. Open a new untitled SQL file
2. Connect to any SQL Server instance
3. Type any multi-line or table-referencing statement e.g. SELECT * FROM TableName WHERE id = 1
4. Place cursor anywhere in the statement
5. Run mssql.runCurrentStatement (MS SQL: Run Current Statement)

Expected: Statement at cursor executes and results appear

Actual: "Failed to start query. Internal Parser Error" is shown

Additional context:

• SELECT 1 on a single line works fine
• Any multi-line statement or real table reference fails 100% of the time
• Highlighting the same statement and running executeQuery works fine
• MSSQL output log shows [info] Started query execution followed immediately by [warning] Attempted to write message but webview is not set then silence
• Manually opening the results pane gives: Cannot read properties of undefined (reading 'toString')
• Tested on multiple extension versions (1.32, 1.40, 1.42.2) — all affected
• Fresh reinstall of extension does not fix it
• Issue is specific to runCurrentStatement — regular query execution works

Steps to Reproduce

1. Open a new untitled SQL file
2. Connect to any SQL Server instance
3. Type any multi-line or table-referencing statement e.g. SELECT * FROM TableName WHERE id = 1
4. Place cursor anywhere in the statement
5. Run mssql.runCurrentStatement (MS SQL: Run Current Statement)
