In the code provided, I found a few issues and suggestions for improvement:

1. In packages/restapi/src/lib/channels/getAllTags.ts:

   • In the GetAllTagsOptionsType, the filter property is of type string, but it might be more appropriate to define it as one of the specific filter types like "PUSH" or "USER".

2. In packages/restapi/src/lib/channels/getChannels.ts:

   • In the getChannelsOptionsType, the filter property is defined as a number, but in the implementation, it seems to be used as a string. Make sure the property type matches its usage.

3. In packages/restapi/src/lib/channels/search.ts:

   • There are multiple ellipses (...) and unfinished comments in the file. These should be reviewed and completed as required.
   • There is a missing closing brace for the search function definition at the end of the file.

4. In packages/restapi/src/lib/constantsV2.ts:

   • There is a typo in the Notification enum definition, it should be Notification instead of Notifictaion.
   • The SEARCH enum property is not defined in the CONSTANTS object.

5. In packages/restapi/src/lib/pushNotification/channel.ts:

   • The search function is missing a closing curly brace which will result in a syntax error.
   • Error handling inside the subscribers method seems inconsistent, with some code paths missing appropriate error handling.

Overall, the structure and logic seem fine, but these issues need to be addressed for better code quality and consistency.

If you make the necessary corrections, please let me know so I can re-review the updated code.
