Hi all,

I'm trying to save my Forms data in blob using the official documentation https://our.umbraco.org/documentation/Add-ons/UmbracoForms/Developer/IFileSystem/

Unfortunately, with the steps from official documentation in backoffice at forms sections I get this error:

An error occured

The argument must not be empty string.  Parameter name: blobName

EXCEPTION DETAILS

Any advice is appreciated.

Ditto the question. Another bug is that you cannot exactly follow the documented configuration.

The following doesn't work and last parameter "useDefaultRoute" has to be commented out because Azure filesystem provider's constructor doesn't accept 5 arguments.

<Provider alias="forms" type="Our.Umbraco.FileSystemProviders.Azure.AzureBlobFileSystem, Our.Umbraco.FileSystemProviders.Azure">
    <Parameters>
        <add key="containerName" value="form-data"/>
        <add key="rootUrl" value="http://[ACCOUNTNAME].blob.core.windows.net/"/>
        <add key="connectionString" value="DefaultEndpointsProtocol=https;AccountName=[ACCOUNTNAME];AccountKey=[YOURACCOUNTKEY]"/>
        <!--
            Optional configuration value determining the maximum number of days to cache items in the browser.
            Defaults to 365 days.
        -->
        <add key="maxDays" value="365"/>
        <!--
            When true this allows the VirtualPathProvider to use the default "media" route prefix regardless 
            of the container name.
        -->
        <add key="useDefaultRoute" value="true"/>
    </Parameters>
</Provider>

On a totally another note, switching to azure filesystem provider has other effects on front end. At least one other bug is that content tree renders newly created forms twice. One version appears as usually and another under a tree note with form GUID

Hi Florin,

I managed to solve this problem on our end. The problem was outdated nuget package. The package is beta/pre-release and by default doesn't show that it has updates. I ended up updating it to the latest version version - 0.5.8 Beta - Forms started to work correctly as per Umbraco documentation.

https://www.nuget.org/packages/UmbracoFileSystemProviders.Azure/

Hi Alex,

Unfortunately, I can't confirm that it works. I have just installed the latest Nuget package(0.5.8) and I still have the issue.

With direct dll from this project https://github.com/JimBobSquarePants/UmbracoFileSystemProviders.Azure it works except that form attached files are stored in wrong place (in media container).

Thanks, Florin

So, you don't get the error from your OP in some cases? At least that error got resolved in my case. Check what is the difference in your project when you install the nuget package and when reference dll files manually. What happens with your configuration files in both cases? I added package via nuget.

Regarding Media folder, it should be controlled by this property:

<add key="useDefaultRoute" value="true"/>

Setting the value to false should fix/remove media folder. I haven't tested it though.
