Summary

This PR removes the assigned @ts-ignore / @ts-expect-error suppressions and replaces them with explicit TypeScript-safe handling.

Changes

Task A — CRUD validation helpers

File: modules/database/src/utils/utilities.ts
Lines: 199–224

Object.keys() returns string[], so TypeScript could not safely index crudOperations[op] or nested fields. I narrowed the dynamic keys to keyof CrudOperations / keyof typeof operationConfig, stored the operation config in a typed local variable, and removed the three @ts-ignore comments.

Task B — DB transform / allowNull

File: modules/database/src/adapters/utils/database-transform-utils.ts
Lines: 123–124

objectField is typed as Indexable, so TypeScript could not assume objectField.required was a boolean. I added an explicit isBoolean(objectField.required) guard and simplified the assignment to res.allowNull = !objectField.required, removing the @ts-expect-error.

Task C — Default schema permissions

File: modules/database/src/adapters/DatabaseAdapter.ts
Lines: ~472–496

Object.keys(defaultPermissions) returns string[], and permissions is optional in the schema type. I added a typed helper for assigning default permissions, typed the keys as Array<keyof typeof defaultPermissions>, and removed the @ts-ignore.

Task D — Mandrill mail transport

File: modules/email/src/email-provider/transports/mandrill/MandrilProvider.ts
New file: modules/email/src/types/nodemailer-mandrill-transport.d.ts

nodemailer-mandrill-transport does not provide TypeScript declarations. I removed the @ts-expect-error from the import and added a local module declaration file for the package.

Task E — Stream → buffer

File: modules/storage/src/utils/index.ts
Lines: 16–35

The original implementation used Buffer.concat(chunks), but this project’s typings report Buffer as incompatible with Uint8Array. I typed the stream and chunk input, normalized chunks to Buffer, and used a narrow local cast at the Buffer.concat call instead of suppressing the error.

Task F — Invitation delete

File: modules/authentication/src/Authentication.ts
Lines: 679–684

The delete query uses Mongo-style dotted keys (data.teamId, data.email), which TypeScript cannot treat as normal Token model properties. I extracted the query into an Indexable object and passed it to deleteOne.

Task G — Authentication handlers

Files:
modules/authentication/src/handlers/metamask.ts
modules/authentication/src/handlers/team.ts

Lines:
metamask.ts: 74, 105, 151
team.ts: 137, 583, 650, 688–695

Several queries and updates used Mongo-style dotted keys such as metamask.ethPublicAddress, metamask.nonce, data.email, and data.teamId. I extracted these into explicit Indexable query/update objects and removed the suppressions.
