Encoding::UndefinedConversionError (“\xFF” from ASCII-8BIT to UTF-8) error for rails 5.1

Question

I am having this error while uploading image. I tried to add activesupport-json_encoder gem in Gemfile as mentioned in https://github.com/carrierwaveuploader/carrierwave/issues/1404, but activesupport-json_encoder does not work with rails 5.2.

Answer 1

You didn't provide enough data, but I guess I had a similar issue before, so try to use utf8mb4 for encoding in your database.yml file and tell me if that fixes it for you
