Export Rules to JSON does not work

[lacyvar]

Clicking on Export Rules to JSON causes an error message on Web client GUI and in the CLI terminal.

To Reproduce

1. Start the Web client GUI: ...\ASA_win_2.3.290> .\asa gui

2. In the Web client, navigate to Author page: http://localhost:5000/author

3. Click on the button Load Embedded Rules --> Embedded rules have been loaded successfully.

4. Click on the button Export Rules to JSON --> A) The message An error has occurred. This application may no longer respond until reloaded. _Reload_ appears in the Web client GUI, B) and this message appears in the CLI terminal:

   fail: Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[111] Unhandled exception in circuit 'p4BsKfPK25Bu9LGOEuXw8ilCX45HWStSLsQm5VXtCco'.

Note: If you click on the Reload, the same issue is coming.

Expected behavior A working feature of exporting rules to a JSON file (with a possibility of specifying the output file name and location).

System Configuration:

• OS: Windows
• OS Version: Windows 10 Pro 21H2
• Application Version: ASA_win_2.3.290
• CLI or GUI: GUI

Thanks for the report. I have a fix that is working locally in #673 which I expect to merge shortly.

Should be fixed in the latest for the zip releases.

After repeating the steps described above, at the step "4. Click on the button Export Rules to JSON", the result is a small file named "Asa-Rules.json" containing only the text "data:text/plain;charset=utf-8,". Thus, it seems the function FileSaveAs gets the filename only and an empty fileContent, even the Rules were loaded before in step 3.
