Hello,
I am encountering issues when I try using RDS 10.11.10. When I am trying to create a New Site, it is failing with the below error. Most of these parameters are depreciated and hence updated Added “collation_server = utf8mb4_unicode_ci”, "innodb_default_row_format = dynamic
", “character_set_server utf8mb4”, and “collation-server utf8mb4_unicode_ci” but still the below issue/error exists. I was referring to the following to update the RDS Parameter Group “https://github.com/frappe/frappe/wiki/Using-Frappe-with-Amazon-RDS-(or-any-other-DBaaS)”. Is there any updated information on setting up parameter group for RDS with version more than 10.11.10 or more?
" For key innodb_file_format. Expected value Barracuda, found value None
For key innodb_large_prefix. Expected value ON, found value None
