Cards are generated with "No content" for some leetcode problems

For a small subset of questions, the generated cards don't capture the question content but instead, have the Content field being No content.

For instance, problem 2340 has such an issue deterministically, while problem 2341 always shows up fine.

Some Leetcode questions with Content field being no content:

• 2339
• 2340
• 2345
• 2346
• 2355
• 2356
• 2361
