unexpected token ",", expected expression in sanity studio vision - reactjs

Question

I am following a course on react native and We are using Sanity as our backend. I have already set the schemas and made the adjustments in my Sanity Studio.
HERE IS MY FEATURED SCHEMA CODE:
export default {
name: 'featured',
title: 'featured Menu Categories',
type: 'document',
fields: [
{
name: 'name',
type: 'string',
title: 'Featured category name',
validation: (Role) => Role.required(),
},
{
name: 'short_description',
type: 'string',
title: 'Short description',
validation: (Role) => Role.max(200),
},
{
name: 'restuarants',
type: 'array',
title: 'Restuarants',
of: [{ type: 'reference', to: [{ type: 'restuarant' }] }],
},
],
};
HERE IS MY RESTAURANT SCHEMA CODE:
export default {
name: 'restaurant',
title: 'Restuarant',
type: 'document',
fields: [
{
name: 'name',
type: 'string',
title: 'Restuarant name',
validation: (Role) => Role.required(),
},
{
name: 'short_description',
type: 'string',
title: 'Short description',
validation: (Role) => Role.max(200),
},
{
name: 'image',
type: 'image',
title: 'Image of the Restuarant',
},
{
name: 'lat',
type: 'number',
title: 'latitude of the restaurant',
},
{
name: 'long',
type: 'number',
title: 'longitude of the restaurant,
},
{
name: 'address',
type: 'string',
title: 'Address of the Restuarant',
validation: (Role) => Role.required(),
},
{
name: 'rating',
type: 'number',
title: 'Enter a rating of (1 - 5)',
validation: (Role) =>
Role.required()
.min(1)
.max(5)
.error('please enter a number between 1 - 5'),
},
{
name: 'type',
type: 'string',
title: 'Category',
validation: (Role) => Role.required(),
type: 'reference',
to: [{ type: 'category' }],
},
{
name: 'dishes',
type: 'array',
title: 'Dishes',
of: [{ type: 'reference', to: [{ type: 'dish' }] }],
},
],
};
I also did one for the dish and category.
Then I went to my Sanity Studio to fill in my restaurant schema fields;
After I went to my Vision Board in Sanity Studio and did a query(Just like the instructor):
*[_type == "featured"]{
...,
restuarants[]=> {
...,
dishes[]=> ,
type=> {
name
}
},
}
And I got an error of:
unexpected token ",", expected expression ;
I did what any developer would have done if they got an error. I double-checked my code and compared it to the instructor in the video. (I still got the error). Then I googled it(And found no answer). It's been 2 days now and I still haven't found anything.
This is my first querying in Sanity and I am not sure what I am doing wrong with my query. Can anyone please help me? Thanks.

Answer 1

As the error mentioned, you missed a ' in your schema code.
Keep a ' after restaurant
{
name: 'long',
type: 'number',
title: 'longitude of the restaurant',
},

Answer 2

No worries I found the answer to my problem. The problem was with my querying.
HERE WAS MY CODE BEFORE:
*[_type == "featured"]{
...,
restuarants[]=> {
...,
dishes[]=> ,
type=> {
name
}
},
}
THIS IS HOW I WAS SUPPOSED TO WRITE IT:
*[_type == "featured"]{
...,
restuarants[]-> {
...,
dishes[] -> ,
type-> {
name
}
},
}
I was supposed to use a straight line instead of an equal sign.
I hope this helps anyone who runs into this problem
