1. What is the problem? Be very detailed.
I cannot reset the app server. I developed an application with two forms, namely household and household_members. I reset the app server, which is odk sync endpoint, successfully on the mid way of the development. After I finalized my survey form I cannot reset the app server. The error message was, "protocol error, please verify that the service and device are compatible". I tried to reset using three Samsung Glaxy Tab A". All produced the same error.
Actually, the resetting start, but it never get to the end. It stopped after syncing the household_member table, with the error message. When I check the tables through the web ui, household_members table was there, but household table was not. (that's why i thought the problem was with household table, but finally found out that not only my household table, other tables with the name 'household' were also not accepted.)
2. What app or server are you using and on what device and operating system? Include version numbers.
My odk tool suits are of 2.1.3 rev 2.3.2. App designer is running on Windows 10 professional. The app server is set up on AWS EC2 linux, t2.small.
3. What you have you tried to fix the problem?
I even tried to reset the server using the sample tables and forms in the app designers. The same error appeared. The strange thing is that when I removed the "household" tables from the sample apps and reset the server using the remaining tables, the reset was successful.
The resetting process is not just rejecting my application, it doesn't accept any table name "household". But when I change my table name from household to another and trying reset, the error reappears.
I also tried restarting the docker stack deploy and rebooting the T2 instance. Nothing seems to be the problem.
My household form is quite big, with 12 user defined sheets and more than one hundred questions.
4. What steps can we take to reproduce the problem?
Whatever I tried is reproducing the problem. I just don't know how not to reproduce the problem.
5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.
I think that 's all . I looked for the odk forum and github page for the solution, I noticed some people have also been facing the problems. I couldn't find out whether they finally got their answer or not.
