I cloned this repo then I have this error when: List All tutorials:

curl --location --request GET 'localhost:8080/api/tutorials' \
--header 'Cookie: X-TIRTA-SESSION=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJwaG9uZSI6IjYyODIzMjA0MDQwOTciLCJpZCI6IjFmYzVjNTU5LTFkZGItNDFlOS04NjAzLWJkOGVlYTEyOTY0ZCIsInVzZXJJZCI6IjRjMWQ1MDJmLTRiYWQtNGQ5MS1iMDdlLTA5Y2IxMDgyMjRkZCJ9.jF5iav9H9mWYxXIrEI_NLpAAHeJBjqd4gAU5dbmk-_c'

Error

Then I tried to add tag into tutorial:

curl --location --request POST 'localhost:8080/api/tutorials/1/tags' \
--header 'Content-Type: application/json' \
--header 'Cookie: X-TIRTA-SESSION=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJwaG9uZSI6IjYyODIzMjA0MDQwOTciLCJpZCI6IjFmYzVjNTU5LTFkZGItNDFlOS04NjAzLWJkOGVlYTEyOTY0ZCIsInVzZXJJZCI6IjRjMWQ1MDJmLTRiYWQtNGQ5MS1iMDdlLTA5Y2IxMDgyMjRkZCJ9.jF5iav9H9mWYxXIrEI_NLpAAHeJBjqd4gAU5dbmk-_c' \
--data-raw '{
    "name": "Spring"

Also got error:
