I'm stuck - Build your first process with Studio (Workflow Part 1)

Hi everyone,

I’ve started learning RPA a few weeks ago (slowly…), and I’m stuck.

I was supposed to create a sequence to automate the retrieval of email attachments from Outlook, and first I kept getting an error (For Each: Unable to cast object of type “System.Char” to type “System.Net.Mail.MailMessage”).

I double and even tripled checked and I had followed the instructions on the video to a T, but every time I debugged it, I kept getting the same error.

So I just deleted the whole all the steps as of the For Each activity and added it all again. When I debugged it, I didn’t get the error message anymore, but I noticed the folder Invoice hasn’t been created, and the attachments are nowhere to be seen.

This is the version of Studio I’m using:

Sorry, too lazy to type all of it

Update:

Even if it’s not displayed in Studio, when I check the folder of the project, the folder Invoices has been created:

I must be doing something wrong, but I can’t figure out what :sweat_smile:

Thanks in advance

Hi @Paz7,

You nave cteated the folder “Invoices”, but the error said " but I noticed the folder Invoice hasn’t been created". Are you sure about the folder? Also, can you remove the "" from "Invoices" and try again ?

Thanks,
Nikos

Hi Nikos,

Thanks for your reply - I tried doing what you suggested, but if I do that, then I get an error too:

I think we’re supposed to always write things with quotation marks (")? Anyway, in the video they used them. So I’m puzzled.

As I said, the folder is not displays in Studio, but it has been created, it’s in the project folder (I suppose as if I hadn’t specified a folder?).

Hi,

Did you try going to Project Panel and clicking the “Refresh” button on the top?

yes of course should use quotation marks (") every time. I suggested to remove the \ (backslash) from the path or use a absolute path to test it

9

yes, no luck :frowning:
i clicked it several times

10

i tried removing the backslash, same problem.

what’s an absolute path and how do i use it?

Anyway, I started a new process from scratch, and it worked. No idea what went wrong

The issue is with using either C# or VB windows -Legacy
This is shown on the bottom right of the project in the blue bar
Its frustrating because for the 2nd part you have to use VB, for this issue you need to use #C when creating the project.

You can also change it by following these steps

  1. Open the “project.json” file in your preferred code editor (I used Notepad++)
  2. Scroll down until you find “expressionLanguage”: “CSharp”,
  3. Change “expressionLanguage”: “CSharp”, to “expressionLanguage”: “VisualBasic”,
  4. Re-launch your project and continue with VisualBasic Legacy.
