Object reference not set to an instance of an object

[valkuc]

Hi. I'm getting "Object reference not set to an instance of an object" when trying to connect to FTP. Could you please tell me where I can find application logs to provide you with more details?

I found logs in settings but those elements are not clickable.

Try click the icon

[valkuc]

Yep, that worked, but not intuitive - it looks like disabled. Anyway, I was able to get logs:

@luandersonn any idea?

[valkuc]

I have updated Mixplorer to the latest version and MyFTP is now able to connect without problems.

[luandersonn]

@valkuc Android FTP Server?

[valkuc]

@luandersonn not exactly, but yes, FTP server. The app name is Mixplorer and it's has ability to act as FTP, HTTP, SMB1 server

[luandersonn]

@valkuc Okay. Can I close this issue?

[valkuc]

@luandersonn yep, you can close it if you don't want to spent time on error handling, because it's not UX to display Object reference is not set to an instance of an object to a regular user :)

[codsec]

@valkuc did u find any other alternative like this software, because looks like the dev is just AFK for this project...

could u tell me how can i do that exacly or share with me your version of this source or even the binary file(it's all i need actually)?

[valkuc]

Sorry, but if you faced that issue when using Mixplorer as a FTP server then you just need to update it on your smartphone. You can do that via Google Play or download it directly from official site. Just goooogle for it. But if you getting thus error with any other FTP server, then I can't help here.

oh im not talking about the apk mixplorer, i mean, how did u get this source(MyFTP) working? because mine i just closes when i try to use's

[valkuc]

No, I did not do anything with MyFTP. For me the problem was solved just by updating FTP server app.

[luandersonn]

I'm migrating the project to the Windows App SDK and hope to fix this bug in the new version #45

Sadly true. Balancing side projects and work is a difficult challenge. But I'm back :)

[codsec]

I'm migrating the project to the Windows App SDK and hope to fix this bug in the new version #45

Could u make it standalone, without windows store etc?
