problem in fetching data from api while using react kanban package

Question

while fetching data locally it works but while fetching data from the api it doesnot displays . `

       <Board
            initialBoard={content}
            renderColumnHeader={({ name, badge }) => (
              <RenderCardTitle name={name} badge={badge} />
            )}
            renderCard={(data, { dragging }) => (
              <CardTaskBox data={data} dragging={dragging} content={content}  >
                {data}
              </CardTaskBox>
            )}
            onNewCardConfirm={draftCard => ({
              id: new Date().getTime(),
              ...draftCard,
            })}
            onCardDragEnd = {onCardMove}
          />

` tried many times but i am not getting the point why this issue is arising??

this completely works when passing local data but not works white passing the data coming from api
