This is what Next.js compiler sends after i try to run up the finished application. i got this error while making the app, then i downloaded the final project and it has the same issue.

replace ur fetchAllProjects with this it will solve the problem `export const fetchAllProjects = (category?: string, endcursor?: string) => { client.setHeader('x-api-key', apiKey);

const query = category ? projectsQuery : getAllProjectsQuery; const variables = category ? { category, endcursor } : { endcursor };

return makeGraphQLRequest(query, variables); };`

hi! thanks for responding, unfortunately nothing has changed, it gives me the same error and i have no idea what to do about it. i have created another query in the graphql index named "getAllProjectsQuery", have changed category and endcursor types to not be null and i get the same error. i am new to typescript and it's so confusing cause there is no proper explanation about how to solve this.

I have the same issue but I'm able to solve it, don't worry it's a common error you have to make some changes in action.ts. and also i will send you my graphql queries

That was a relief man, Thanks a lot. I was so happy when I found someone has corrected the mistake.
