Lambda deployement

I tried using pdftotext for extracting text from pdf. My BE is deployed in AWS lambda. I added this to the dockerfile: `RUN yum install -y poppler-utils && yum clean all` The code i am using is (Go): `func IsTextBasedPDFUsingPoppler(ctx context.Context, fileBytes []byte) (bool, string) { defer func() { if r := recover(); r != nil { logger.Get(ctx).Errorf("Panic in IsTextBasedPDF: %v", r) } }() logger.Get(ctx).Infof("Running pdftotext, pdf_size=%d", len(fileBytes)) // timeout protection - generous timeout for Lambda environment ctxTimeout, cancel := context.WithTimeout(context.Background(), 60*time.Second) defer cancel() env := os.Getenv("ENV") pdfExtractionLibraryPath := "/usr/bin/pdftotext" // Default Linux path for Lambda if env == "qa" { pdfExtractionLibraryPath = "C:\\Program Files\\poppler-25.12.0\\Library\\bin\\pdftotext.exe" } // Log the path being used logger.Get(ctx).Infof("Using pdftotext path: %s (ENV=%s)", pdfExtractionLibraryPath, env) cmd := exec.CommandContext( ctxTimeout, pdfExtractionLibraryPath, "-enc", "UTF-8", "-f", "1", "-l", "5", "-nopgbrk", "-", // read PDF from stdin "-", // write text to stdout ) var stdout bytes.Buffer var stderr bytes.Buffer cmd.Stdout = &stdout cmd.Stderr = &stderr // Get stdin pipe and write PDF bytes, then close it stdin, err := cmd.StdinPipe() if err != nil { logger.Get(ctx).Errorf("failed to get stdin pipe: %v", err) return false, "" } // Start the command if err := cmd.Start(); err != nil { logger.Get(ctx).Errorf("failed to start pdftotext: %v", err) return false, "" } // Write PDF bytes to stdin in a goroutine and close it writeErr := make(chan error, 1) go func() { defer stdin.Close() _, err := stdin.Write(fileBytes) writeErr <- err }() logger.Get(ctx).Infof("Waiting for pdftotext to complete...") // Wait for command to finish err = cmd.Wait() // Check if there was a write error if wErr := <-writeErr; wErr != nil { logger.Get(ctx).Errorf("failed to write to stdin: %v", wErr) } if err != nil { // Check if the binary exists if _, statErr := os.Stat(pdfExtractionLibraryPath); os.IsNotExist(statErr) { logger.Get(ctx).Errorf("pdftotext binary not found at path: %s", pdfExtractionLibraryPath) } logger.Get(ctx).Errorf("pdftotext failed: %v stderr=%s stdout=%s", err, stderr.String(), stdout.String()) return false, "" } extractedText := strings.Join(strings.Fields(stdout.String()), " ") logger.Get(ctx).Infof("pdftotext finished") // simple threshold detection if len(extractedText) < 50 { return false, "" } return true, extractedText }` but the code is not working. Pls help to debug.
