Hello,
I have used pouchDB as my local database in my project, it is working fine in the local machine and normal build, but when I am trying to build with –prod then PouchDB throw me this error.
I have deleted/clear PouchDB before creating a new Document but not worked.
Please refer this image for Error.
My Ionic Info
PouchDB Info from package.json
“pouchdb”: “^7.2.2”,
“pouchdb-adapter-cordova-sqlite”: “^2.0.8”,
Please help me. 
Thanks.
