…t save operations - Configure HTTP server timeouts (requestTimeout: 5min, headersTimeout: 2min, keepAliveTimeout: 65s) - Add better error logging in PUT /scripts endpoint - Improve writeFileWithLock error handling with descriptive messages and proper cleanup - Ensure lock is always released even on error Co-authored-by: whyour <22700758+whyour@users.noreply.github.com>
- Use finally block to ensure file handle is closed even on error - Extract error messages properly using instanceof Error check - Improve error message formatting for better debugging Co-authored-by: whyour <22700758+whyour@users.noreply.github.com>
- Wrap fileHandle.close() in try-catch to prevent masking original errors - Log close errors without throwing to preserve error context Co-authored-by: whyour <22700758+whyour@users.noreply.github.com>
- Add explicit FileHandle type annotation for fileHandle variable - Change fileHandle check from truthy to explicit undefined check - Change release type from null to undefined for better type safety Co-authored-by: whyour <22700758+whyour@users.noreply.github.com>

Script save operations were failing with
ERR_EMPTY_RESPONSEdue to missing HTTP server timeout configuration and inadequate error handling in the file write path.Changes
Server timeout configuration (
back/services/http.ts)requestTimeout: 300000ms,headersTimeout: 120000ms,keepAliveTimeout: 65000msto prevent premature connection drops during file operationsError handling improvements (
back/api/script.ts,back/shared/utils.ts)/api/scriptsendpointwriteFileWithLockwith proper try-catch-finally blocks for file handle and lock cleanupType safety (
back/shared/utils.ts)FileHandletype annotationundefinedfor clearer semanticsExample
Before: File write errors could leave locks unreleased or file handles open, causing subsequent operations to hang or fail.
After:
Locks and file handles are guaranteed to be cleaned up via finally blocks, with distinct error messages for each failure point (create file, acquire lock, write file).
