{"documentId":"unique()","data":{"firstname":"a","lastname":"b","knowledge":"c","full_age":false,"phone_one":"98345679","email":"mail@mail.com"},"permissions":[]}

got this error message when making a POST request to /databases/${dbId}/collections/${collectionId}/documents. is there something wrong with my request body? (see above)

{ message: 'Param "documentId" is not optional.', code: 400, type: 'general_argument_invalid', version: '1.4.13' }

TL;DR

Title: Error: Param "documentId" is not optional Message: Is the request body incorrect? The developer encountered an error when making a POST request to create a new document. The error message states that the "documentId" parameter is not optional. The developer provided the request body in the message, and it appears to be correct. Solution: The "documentId" parameter is required in the POST request. Ensure that a valid value is provided for the "documentId" in the request body. If using a custom ID, make sure it is correctly formatted and meets any requirements specified by the API.
