Microservice exercise is not marking as complete eventhough it shows it as correct when submit

Hello I am submitting glitch and github urls for projects " Request Header Parser Microservice" and " File Metadata Microservice". They both accept the code and promote me to next exercise but never mark my exercise as complete. My project output is correct. Due to this, it does not offer me certificate. Here are my urls for project “File Metadata Microservice”. Please let me know why its not working.

Glicth: https://hfile-metadata-microservicek-.glitch.me
Github: https://github.com/hassandad/metadata-microservice

Please tell me why its not marking my answer as correct but still showing that my answer is correct and also sending me to next exercise.
