Typescript error on plugin schema reference field

When creating plugin for table schema, and adding reference to another table (e.g. user) I get TS error that instaed of reference it should be references

Object literal may only specify known properties, but 'reference' does not exist in type 'FieldAttribute<FieldType>'. Did you mean to write 'references'?ts(2561)
auth-C42JqOR9.d.ts(1893, 17): The expected type comes from property 'userId' which is declared here on type '{ [x: string]: FieldAttribute<FieldType>; }'
(property) reference: {
    model: string;
    field: string;
    onDelete: string;
}

    model: string;
    field: string;
    onDelete: string;
}

My code:

 fields: {
          userId: {
            type: 'string',
            required: true,
            unique: true,
            reference: {
              model: 'user',
              field: 'id',
              onDelete: 'cascade',
            },
          },

 fields: {
          userId: {
            type: 'string',
            required: true,
            unique: true,
            reference: {
              model: 'user',
              field: 'id',
              onDelete: 'cascade',
            },
          },

const tosPlugin = () => {
  return {
    id: 'tos-plugin',
    schema: {
      TermsOfService: {
        fields: {
          userId: {
            type: 'string',
            required: true,
            unique: true,
            reference: {
              model: 'user',
              field: 'id',
              onDelete: 'cascade',

oh it's references not reference

Augustas PaliulisOP•2d ago

Is it? Because when I change to references I get an error during migration. With reference everything works find

bekacru•2d ago

what is the error?

Augustas PaliulisOP•2d ago

can't tell you specifically, just that when using reference it is successful and also in documentation it's reference instead of references

maybe remove onDelete cascade incase that's the issue

Augustas PaliulisOP•2d ago

Already tried that, it doesn't help

bekacru•2d ago

so npx @better-auth/cli migrate is failing when you add references?

Augustas PaliulisOP•2d ago

Well at least for me. Only works when it is reference
