collection_size_error: TOO_MANY

[Ajit Trivedi]

On trying to upload a user to google ads API I am getting the error as collection_size_error: TOO_MANY. I am using the following code snippet to upload users to the audience created in google ads API.

Set userList; //userList contains the hashed email of the user that i want to upload to the audience

List<UserDataOperation> userDataOperations = new ArrayList<>(userList.size()); for (String user : userList) { UserDataOperation userDataOperationEmail = UserDataOperation.newBuilder().setCreate( UserData.newBuilder() .addUserIdentifiers(UserIdentifier.newBuilder().setHashedEmail(user).build()) .build()).build(); userDataOperations.add(userDataOperationEmail); } UploadUserDataRequest.Builder uploadUserDataRequest = UploadUserDataRequest.newBuilder().setCustomerId(clientCustomerId) .setCustomerMatchUserListMetadata( CustomerMatchUserListMetadata.newBuilder().setUserList(resourceName).build()); uploadUserDataRequest.addAllOperations(userDataOperations); try (UserDataServiceClient userDataServiceClient = googleAdsClient.getLatestVersion() .createUserDataServiceClient()) { response = userDataServiceClient.uploadUserData(uploadUserDataRequest.build()); }

What I have observed is that if my userList contain more then 10 values than I get this error.

Thanks
