Describe the bug
Ecovacs Home 2.4.4 for Android shows Java error seen in attached screen capture ("Value Y of type java.lang.String cannot be converted to JSONObject(null,-1)") when I click the Log In button. I do not face this problem when using Ecovacs Home 2.0.0 on same Android device.

To Reproduce
Steps to reproduce the behavior:

Install Ecovacs Home 2.4.4 on Android device. Device should already have bumper CA certificate. In my case I am using Android 6.0.
Run the app and accept the agreements/policy statements. Login screen will display.
Fill the email and password fields and click Log In button.
Java error appears, and app does not login.

Expected behavior
Expect the app to login and proceed to list of robots.

Screenshots
Screenshot attached.

@lehoangnb : Thanks for your response. Should I put the literal string "public key or something" or should I replace it with the public key of the bumper certificate? I am using docker image so I am not sure how to propagate this change to docker image.

I have decrypted the packet from ecovacs app to the server using mitm, I see that is a random string like md5.
Just change the file and rebuild docker image
If u dont want to change anything, use older version of ecovacs app (2.1.3 or below)
