To resolve the issue of infinite requests being sent to the server from the hashtag endpoint, I took the following steps:

1. Wrote a test to confirm that multiple requests were indeed being made to the server.
2. Normalized the incoming hashtag to ensure it matches the format of the current hashtag, if one already exists.
3. Modified the logic to fetch the hashtag only if it doesn't already exist.
