      owner: a.string().required(),
    })
    .authorization([a.allow.public()])
    .secondaryIndexes((index) => [index("owner")]),
  Article: a
    .model({
      content: a.string(),
      owner: a.string().required(),
    })

Hey @kekami, Thank you for raising this. We can reproduce the issue by following the description. Hence, marking this as a bug for the team to evaluate further.

@kekami , As an alternative solution, you can utilize the queryField to designate a custom name for the query, as demonstrated below. Please inform us if this assists in moving forward.

const schema = a.schema({
  Todo: a
    .model({
      content: a.string(),
      owner: a.string().required(),
    })
    .authorization([a.allow.public()])
    .secondaryIndexes((index) => [index("owner")]),
  Article: a
    .model({
      content: a.string(),
      owner: a.string().required(),
    })
    .authorization([a.allow.public()])
    .secondaryIndexes((index) => [index("owner").queryField("listByArticleOwner")]),
});
