Cannot override column type to json

[anishjain94]

Hi I am trying to override a column type to json. I am not able to do that. Can you help me with it.
As per this documentation clickhouse still supports JSON.
https://clickhouse.com/docs/en/integrations/go#json
Here are my models.

type LogKarzaApiClickhouse struct {
	ch.CHModel `ch:"table:log_karza_apis"`
	RequestId       string                 `ch:"request_id"`
	Path            string                 `ch:"path"`
	Request         []byte                 `ch:"request"`
	Response        []byte                 `ch:"response"`
	ResponseRaw     string                 `ch:"response_raw"`
	Method          common.HttpMethodsEnum `ch:"method"`
	StatusCode      int                    `ch:"status_code"`
	RequestHeaders  *common.CustomHeader   `ch:"type:JSON,request_headers"`
	ResponseHeaders *common.CustomHeader   `ch:"type:JSON,response_headers"`
	ResponseTime    time.Duration          `ch:"response_time"`
	Error           *string                `ch:"error"`
}

Function

func TestCreateTable(t *testing.T) {
	fmt.Println("cache")
	ctx := context.Background()
	environment.InitializeEnvs(environment.VARIANT_LOAN)
	logger.InitializeLogger()
	uptrace.InitializeClickHouse()

	res, err := uptrace.Clickhousedb.NewCreateTable().Model((*LogKarzaApiClickhouse)(nil)).Exec(ctx)
	util.AssertError(err, util.BLOCKED, http.StatusBadGateway, "error")

	util.PrintJson(res)
}
