I am struggling with Type error on nextjs

JavaScript
1

When I was ready to deploy, I wrote npm run build in my nextjs application, I got this error.

The problem is that I don’t know what it is or where to look, I leave the link to my repository if you want to take a look, thanks in advance

Type error: Type ‘{ tag: “POST”; param_position: “first”; param_type: { json(): { name: any; email: any; password: any; } | PromiseLike<{ name: any; email: any; password: any; }>; method: string; body: { …; }; }; }’ does not satisfy the constraint ‘ParamCheck<NextRequest | Request>’.
Types of property ‘param_type’ are incompatible.
Type ‘{ json(): { name: any; email: any; password: any; } | PromiseLike<{ name: any; email: any; password: any; }>; method: string; body: { name: any; email: any; password: any; }; }’ is not assignable to type ‘NextRequest | Request’.
Type ‘{ json(): { name: any; email: any; password: any; } | PromiseLike<{ name: any; email: any; password: any; }>; method: string; body: { name: any;
email: any; password: any; }; }’ is missing the following properties from type ‘Request’: cache, credentials, destination, headers, and 14 more.

148 | Diff<
149 | ParamCheck<Request | NextRequest>,

150 | {
| ^
151 | tag: ‘POST’
152 | param_position: ‘first’
153 | param_type: FirstArg<MaybeField<TEntry, ‘POST’>>

Can’t you just use (req: Request) for the route handler parameter?

That works, thanks, but I have another similar problem. Can I put it here or do I need to create another post?

If it is for the same project it would be best if you asked it here.
