I am trying to finish the freecodecamp Backend Development and APIs projects curriculum. However, I encountered a problem when I submit the solution to one of the microservices.
I have finished successfully 4 microservices except for the request header parser microservice as whenever I submit the solution it normally prompts me that I have
submitted the right solution successfully.However, as soon as I refresh the page it shows me that the challenge is unsolved.
see the below image which shows that I have successfully submitted the correct solutions.
After I refresh the page, the check mark beside the request header parser microservice will disappear.
Please advise me on what to do to fix this issue as I have been struggling for a while with this issue, I can’t claim my certificate because of this.
