Cannot install custom app on v11

Updating DocTypes for wela : [============================ ]

There was an issue while migrating the DocType: Generate Spreadsheets

File “/home/jvfiel/frappe-v7/apps/frappe/frappe/core/doctype/doctype/doctype.py”, line 247, in on_update
raise e
pymysql.err.ProgrammingError: (1064, u’You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '“”,\n_comments text,\n_user_tags text,\nfilter_level varchar(140),\n`grading_s' at line 24’)

Has anyone experienced the same?

No.
I have multiple Custom apps on V11 which we tested.

I was able to install/Uninstall custom app.

I faced an issue like this but it was from the Custom App git pull side and not from V11 bench side.

Can you try doing manual git pull and check it returns success or any error.

Hi, yes I can manually git pull the app.
