Error message

result.Error

What it means

Thrown by ServicesClient.UploadDiagPackage when the POST to /playnite/diag returns a ServicesResponse<Guid> whose Error field is non-empty. The diagnostic-upload handler on the services proxy reported an error (size limit, server fault, storage failure), and the client re-throws the server's message.

Solutions

1. Read the captured Error text from the log to determine whether it's size, storage, or auth related.
2. If the diag file is large, retry once after a backend restart or contact support; the server-side cap may need raising.
3. Verify Endpoint (ServicesUrl) resolves to the current service and the Playnite-Version header is set.
4. On persistent failure, fall back to saving the diag locally and sharing it manually.

Example fix

// before
var id = client.UploadDiagPackage(diagPath);

// after
try { return client.UploadDiagPackage(diagPath); }
catch (Exception ex)
{
    logger.Error(ex, "Diag upload failed; saving locally");
    File.Copy(diagPath, Path.Combine(localDir, Path.GetFileName(diagPath)));
    throw;
}

if (!File.Exists(diagPath)) throw new FileNotFoundException(diagPath);
var size = new FileInfo(diagPath).Length;
if (size > MaxDiagBytes) throw new InvalidOperationException($"Diag package too large: {size}");

static bool CanUploadDiag(string path) => File.Exists(path) && new FileInfo(path).Length <= MaxDiagBytes;

try { return client.UploadDiagPackage(diagPath); }
catch (Exception ex)
{
    logger.Error(ex, "Diag upload failed; keep local copy");
    File.Copy(diagPath, Path.Combine(localFallbackDir, Path.GetFileName(diagPath)), overwrite: true);
    throw;
}

When it happens

Trigger: UploadDiagPackage(diagPath) POSTs the file stream to Endpoint+'/playnite/diag'; the response body deserializes with a non-empty Error at line 48. The server accepted the connection but failed to ingest the package.

Common situations: Diag package exceeds the server's max body size. Backend storage (blob/db) temporarily unavailable. ServicesUrl points to a stale endpoint that returns an error envelope. Auth/anti-abuse layer on the proxy rejected the upload.
