I have a JSON in the following format https://pastebin.com/Ep6zSgFU, and I have the following code to store it as a JSON object https://pastebin.com/m5R5v67w.
The compiler complained that my columns object does not have any exported field, nor custom marshalling. I couldn't load my JSON file into the nested object.
How should I proceed with this problem? Sorry I am quite new to Golang.
