Nil fileUrlsToBatchResultEntries response when setting template name and value to DBFILESCommitInfo

[mms]

Hello there.

I am trying to set a property custom property to a file that I am uploading to User's folder with the name 'name' and value 'value', with teamplate '/templateId'. When I add the following I get a nil fileUrlsToBatchResultEntries and as consequence nil result, however the file is indeed uploaded to the applications' folder.

        NSMutableDictionary<NSURL *, DBFILESCommitInfo *> *uploadFilesUrlsToCommitInfo = [NSMutableDictionary new];
        NSDictionary *attributes = [[NSFileManager defaultManager] attributesOfItemAtPath:localFilePath error:nil];
        NSArray *propertyGroupArray = [NSArray arrayWithObjects:[[DBFILEPROPERTIESPropertyGroup alloc] initWithTemplateId:@"/templateId" fields:[NSArray arrayWithObjects:[[DBFILEPROPERTIESPropertyField alloc] initWithName:@"name" value:@"value"], nil]], nil];
        DBFILESCommitInfoWithProperties *commitInfo = [[DBFILESCommitInfoWithProperties alloc] initWithPath:cloudFilePath mode:[[DBFILESWriteMode alloc] initWithOverwrite] autorename:[NSNumber numberWithBool:NO] clientModified:attributes[NSFileCreationDate] mute:[NSNumber numberWithBool:YES] propertyGroups:nil strictConflict:[NSNumber numberWithBool:YES]]
        [uploadFilesUrlsToCommitInfo setObject:commitInfo forKey:[NSURL fileURLWithPath:localFilePath]];
        [client.filesRoutes batchUploadFiles:uploadFilesUrlsToCommitInfo queue:nil progressBlock: {} responseBlock:^(NSDictionary<NSURL *,DBFILESUploadSessionFinishBatchResultEntry *> *fileUrlsToBatchResultEntries, DBASYNCPollError *finishBatchRouteError, DBRequestError *finishBatchRequestError, NSDictionary<NSURL *,DBRequestError *> *fileUrlsToRequestErrors){         
                DBFILESMetadata *dbFilesMetadata = nil;
                DBFILESUploadSessionFinishBatchResultEntry *result = fileUrlsToBatchResultEntries[[NSURL fileURLWithPath:localFilePath]];
                if (result) {
                    if (result.tag == DBFILESUploadSessionFinishBatchResultEntrySuccess)
                        dbFilesMetadata = result.success;
                    else
                        aError = [self errorFromRouteError:finishBatchRouteError requestError:finishBatchRequestError];
                } else
                    aError = [self errorFromRouteError:finishBatchRouteError requestError:finishBatchRequestError];
                success = (dbFilesMetadata != nil);
        }];

What am I doing wrong when trying to set a property name and value to the file that I want to upload, please?

Looking forward to your response.

If the file does get uploaded, fileUrlsToBatchResultEntries shouldn't be nil, so we'll be happy to help look into it. Is this is actual code you're running though, or was it edited for the post? I ask because it looks like you may be missing some curly brackets. Also, it looks like you're not using the propertyGroupArray anyway.

To begin debugging this, it may be helpful to start by just printing out all of the values given to the response block, e.g.:

NSLog(@"fileUrlsToBatchResultEntries: %@", fileUrlsToBatchResultEntries);
NSLog(@"finishBatchRouteError: %@", finishBatchRouteError);
NSLog(@"finishBatchRequestError: %@", finishBatchRequestError);
NSLog(@"fileUrlsToRequestErrors: %@", fileUrlsToRequestErrors);

I found the solution following the source:

The problem was that I was trying to set the property while having a folder access only.

Cheers.
