B4J Question Using PowerShellConvertToPdf with JRDC2 (SOLVED)

LGS said:

Hello everyone
I am creating a pdf file in a Handle(JRDC2) using PowerShellConvertToPdf

PostString is sent from B4A:

Dim j As HttpJob
j.Initialize("", Me)
j.PostString(link,dataToPdf)
Wait For (j) JobDone(j As HttpJob)
If j.Success Then
   Log("<" & j.GetString & ">")
End If

In the Handle(req As ServletRequest, resp As ServletResponse):

try
   WD.PowerShellConvertToPdf(FileIn,FileOut, False)
   resp.Write("Created PDF")
catch
   Log(LastException)
   resp.Write("Not Created PDF")
End Try

Ok, so far so good. The pdf file is created

B4A immediately shows::

Log("<" & j.GetString & ">") => "<Created PDF>"

But on the server, PowerShellConvertToPdf takes about 3 seconds to create the pdf file.
So I understand that when B4A receives in j.GetString "<Pdf Created>", in reality the file does not yet exist on the server.

What I need?
Validate that the pdf file has been created successfully

What have I tried to do?

Use Wait for:

'I changed this:
WD.PowerShellConvertToPdf(FileIn,FileOut, False)
resp.Write("Created PDF")

'For this
Wait For (WD.PowerShellConvertToPdf(FileIn,FileOut, False)) Complete (Success As Boolean)
If Success Then
    resp.Write("Pdf Creado")
Else
    resp.Write("Pdf No Creado")
End If

Result in B4A:
Log("<" & j.GetString & ">") => "<>"

Second try::

WD.PowerShellConvertToPdf(FileIn,FileOut, False)
Dim exists As Boolean = False
Do While exists = False
    If File.Exists(dir, name) Then
        exists = True
        Log("already created")
    Else
        Sleep(400)
        Log("wait")
    End If
Loop
resp.Write("Created PDF")

Result in B4A:
Log("<" & j.GetString & ">") => "<>"

How can I validate in the Handle that the pdf file was created successfully, so that B4A receives "Pdf Created"?

I appreciate any ideas or suggestions.

'Modify your handle class'

Sub Handle(req As ServletRequest, resp As ServletResponse)
    ConvertToPdf(req ,resp)
    StartMessageLoop
End Sub

Sub ConvertToPdf(req As ServletRequest,resp As ServletResponse)
    ......
    ......
    WD.PowerShellConvertToPdf(FileIn,FileOut, False)
    resp.Write("Created PDF")

    'For this
    Wait For (WD.PowerShellConvertToPdf(FileIn,FileOut, False)) Complete (Success As Boolean)
    If Success Then
        resp.Write("Pdf Creado")
    Else
        resp.Write("Pdf No Creado")
