It’s become quite difficult because the entire set of responses has changed. Not just that even the relations have data and attributes fields which make it quite complicated to deserialise the responses.
I thought v4 would be a change in the structure/working of Strapi but the change is huge in terms of outputs. It’s breaking lots of stuff for me.
It’s good that I still have the Strapi v3 instance installed on a separate server, else it’s pretty hard to update everything.
