Working with filter: filter is not a function issue

I’m using spread to “merge” the objects from my functions into a single object. I want to check if the values I’m sending at my “profiles” array of strings matches any of the values at the merged object and print them.

async getAll() {
    try {
      const triangles = await this.getAlltriangles(true);
      const squares = await this.getAllsquares(true);
      const circles = await this.getAllcircles(true);

      const output = {
        ...triangles, ...squares, ...circles,
      };

      
      console.log('unified list:', output);
      console.log(typeof (output)); // just double checking if the outcome is an array indeed
      return output;
    } catch (error) {
      this.logger.error(error);
    }
  }

The next function will try doing the operation. I’m trying to work with filter and includes:

async findProfiles(profiles: string[], authorizedUser: string) {
    if (!authorizedUser) return 'Invalid User';
    if (!profiles || profiles.length === 0) {
      return 'No profiles were informed';
    }
    try {
      await this.getAll();
      const getAllarray = await this.getAll();
      const matches = getAllarray.filter((obj) => profiles.includes(obj.name));

      console.log(matches);
      return { matches };
    } catch (error) {
      console.log(error);
      return error;
    }
  }

this line const matches = getAllarray.filter((obj) => profiles.includes(obj.name)); returns me an empty object instead ,along with a TypeError: getAllarray.filter is not a function
