I'm trying to upload files to Appwrite's storage bucket using the REST API, but I keep encountering the following error:

TypeScript
{
    "message": "Param \"fileId\" is not optional.",
    "code": 400,
    "type": "general_argument_invalid",
    "version": "1.6.1"
}

What I’ve Tried:

  1. I'm using a fileId generated by UUID.randomUUID() in Java, but I still get the error. Here's an example of the fileId I'm sending: 123e4567-e89b-12d3-a456-426614174000.
  2. I’ve also tried passing ID.unique() in the payload for fileId, but it doesn’t seem to work.

Here's my code;

TypeScript
public Map<String, Object> uploadFile(MultipartFile file) throws Exception {
    String url = appwriteEndpoint + "/v1/storage/buckets/" + appwriteBucketId + "/files";

    String fileId = UUID.randomUUID().toString().replace("-", "").substring(0, 36);

    Map<String, Object> operations = new HashMap<>();
    operations.put("query", "mutation CreateFile($bucketId: String!, $fileId: String!, $file: InputFile!) { storageCreateFile(bucketId: $bucketId, fileId: $fileId, file: $file) { id } }");
    Map<String, Object> variables = new HashMap<>();
    variables.put("bucketId", appwriteBucketId);
    variables.put("fileId", fileId);
    variables.put("file", null);
    operations.put("variables", variables);

    // Build multipart request here (details omitted for brevity)...
}

Questions:

  1. Are there additional constraints for the fileId parameter that I might be missing?
  2. Is there something wrong with the way I’m structuring the multipart/form-data payload?
  3. How should ID.unique() be handled if passed programmatically via REST?
TL;DR
Issue: Developers facing an error message stating "Param 'fileId' is not optional" when trying to upload files to Appwrite's storage bucket via the REST API. Solution: 1. Ensure the fileId for the file is properly generated, try using UUID.randomUUID().toString() without modification. 2. Check if the multipart/form-data payload structure aligns with Appwrite's requirements. 3. Handle ID.unique() appropriately when passing it programmatically via REST to avoid errors.
