I know this question is not new, but please help me solve this problem. I have created an spring boot app in server role. and I have tried to deploy this to heroku, and create database host on heroku too, but when I tried to run it failed with error: SELECT command denied to user ....., I guessed because of its security. So my question is: Do you have any host free that can recommend to me? or do you know how to solve my issue. Thank you very much Sorry for this dumb question and wrong grammar.
