Understand how Context works in test environment with Identity

Hi Everyone, I'm a bit confused about the context in my test. Here's what I'm trying to achieve: I want to check if a user can access a document created by another user. To do this: 1 - I created an identity (asViewer) for the user (viewer) who wants to access the document. 2 - Then, I verified that the owner of the document can retrieve this user by using t.run. This part works fine. 3 - Next, I called my mutation, which is responsible for adding permissions to the document for the viewer. I executed this mutation with the asOwner identity, but it throws an error. The mutation is unable to retrieve the viewer user. Here is the relevant part of my code:

const { asUser: asViewer, user: viewer } = await createIdentity(t);
const getViewerAsOwner = await asOwner.run(async (ctx) => {
    return await ctx.db.get(viewer._id);
});

asOwner.mutation(api.core.permissions.insert, {
    subjectId: viewer._id,
    entityId: ownedApplication._id,
    entityType: 'applications',
    role: 'viewer',
});

I don't understand why I'm able to retrieve the viewer user when I execute asOwner.run, but not when I execute asOwner.mutation. Did I miss something? Could someone explain this behavior to me? Thank you

CustomFunctions, vitest and multiple query call in a query

Hi everyone, I'm struggling on a test. Vitest throw an error as below :


 ❯ Module.checkIfAuthorizedToCreateObject convex/validator.ts:9:15
      7|   ctx: GenericMutationCtx<DataModel>
      8| ) => {
      9|   const sub = await ctx.runQuery(api.subscriptions.getSubscriptionInformation)
       |               ^


{
  stack: 'Error: \n' +
    '    at performAsyncSyscall \n' +
    '    at runUdf \n' +

It's a query which is called inside a query (customQuery). I don't understand why, there are some limitations with vitest when we use custom functions or when we call queries in a query ? thank you

custom functions and getAll helper

Hi everyone🙂 , I create two custom functions to handle my queries and mutations. Now, when I use the getAll helper as below I have some strange errors. Except that I can query or mutate everything with my customFunctions. Do you have any idea what is the problem ? Did I do something wrong with my custom Functions ? Thanks 🙏 GetAll :

 applicationsToUpdate = await getAll(
          ctx.db,
          childrenApplicationsIds.map((x) => x as Id<'applications'>)
);

Here, thrown errors : Uncaught TypeError: Cannot read properties of undefined (reading 'reader') or Uncaught TypeError: Cannot read properties of undefined (reading 'db') My customs functions:

export const SecureMutationBuilder = customMutation(mutation, {
  args: {},
  input: async (ctx, args) => {
    const { userId, userPermissions } = await getPermissions(ctx);
    const db = wrapDatabaseWriter(
      { userId },
      ctx.db,
      await rlsRules(ctx, userId, userPermissions)
    );
    return { ctx: { db, userId, userPermissions }, args };
  }
});

export const SecureInternalMutationBuilder = customMutation(internalMutation, {
  args: {},
  input: async (ctx, args) => {
    const { userId, userPermissions } = await getPermissions(ctx);
    const db = wrapDatabaseWriter(
      { userId },
      ctx.db,
      await rlsRules(ctx, userId, userPermissions)
    );
    return { ctx: { db, userId, userPermissions }, args };
  }
});
