{ allow: public, operations: [read] }
{ allow: groups, groups: ["admin"], operations: [read] }
{ allow: private }
]
) {
id: ID!
key: String!
name: String!
symptoms_common: [Symptom] @manyToMany(relationName: "BodyAreaSymptomCommon")
symptoms_all: [Symptom] @manyToMany(relationName: "BodyAreaSymptomAll")
body_parts: [BodyPart] @hasMany(indexName: "byBodyArea", fields: ["id"])
}

type BodyPart
@model
@auth(
rules: [
{ allow: public, operations: [read] }
{ allow: groups, groups: ["admin"], operations: [read] }
{ allow: private }
]
) {
id: ID!
key: String!
name: String!

type Symptom
@model

{ allow: groups, groups: ["admin"], operations: [read] }
{ allow: private }
]
) {
id: ID!

dewey: String!
body_area_common: [BodyArea] @manyToMany(relationName: "BodyAreaSymptomCommon")

### Expected behavior

Works when push backend accept connections on content page crash amplify studio so I tried deleting what I had and doing it through studio but it won't let me

### Reproduction steps

use schema provided try and add data in content section and fails if try a m:m connection so try just using data section to create the autogenerated connections but doesnt work for more than one but i need a list of all symptoms and common so need both. Which works completely fine on everything. outside of amplify studio like appsync or from my front end

### Build Settings

_No response_

### Additional information

_No response_

Start with the provided GraphQL schema and reproduce the failure in Amplify Studio's Content and Data sections using multiple many-to-many relations. Compare the behavior with AppSync or the frontend, then confirm that both common and all symptom connections can be created and managed without the Studio page crashing.
