Help Needed career switch From automation to Development

Short version:-So guys I am working as an automation tester wanted to switch to Development?

Long version:- So i joined my current company as fresher.Had basic knowledge of java then was trained on java spring boot Microservices devlopment. Then put on bench for about 5 month(i actually wasted that time).Now got a project I do automation using python and selenium.I don't like doing it . So now I want to switch to development. Confused should i learn Django, Node js or should stick with java spring only. I am more inclined towards django as now i write automation script in python. And i personally feel it to be better then java (maybe cause it is easier to write).But i don't know market trends. That's why guidance needed.Thanks in advance
