I ran into an issue.
I tried to install my own custom app on a newly created site and it throws me an error of:
pymysql.err.InternalError: (1069, u’Too many keys specified; max 64 keys allowed’)
After debugging I found out that system is trying to run an ALTER query like below
ALTER TABLE tabDeleted Document MODIFY
I found out it tried to create some indexes on table tabDeleted Document but it couldn’t.
My first question is, can someone explains this behaviour?
Secondly, when I tried to install the app again, it gives me primary key duplication error because some of the data was already migrate during first installation attempt.
is there a way to smoothly install an app which encounters error during isntallation?
