Content creation

Hello, I wanted to use the Dialog Cards to process  test questions in Moodle. However, I cannot find a way to import these approx. 6,000 to 7,000 questions into H5p or Moodle. The question consists of text and image and the reverse side also consists of the question and image and the answers in text format. How can I import these questions and images and answers into the H5P Dialog Card?

Whenever I make some changes in H5P anc click Save. I am getting the error "Error writing to database". And I am not able to see the H5P that I created. Any idea why this error is coming? I am facing this issue recently only.
