Method Directive Error - Unable to use Custom Code

[klincecum (Kevin Lincecum)]

Yeah we’re lost too. Mine was fixed with a simple install of the .NET 6 SDK.

It seems this symptom can manifest many ways.

[Heide (Heide Warren)]

Hello,
I wanted to provide an update. I have un-installed and re-installed Epicor a third time. I have not found a fix for my problem yet.

My problem keeps getting worse. Epicor Pilot had an update over the weekend. We are a multi-tenant customer and receive all updates.

Now I am not able to get into the Part, Part Tracker, and Part Transaction History Tracker. Each screen errors out with the following message:

This problem is with my workstation. I can go to another workstation and login using my credentials and have no errors. I am also a system administrator and there was mention that it is affecting system admins.
I am at a lose on how to fix this issue and advice would be helpful.

[klincecum (Kevin Lincecum)]

At this point I would cut my losses and reinstall Windows, just to be honest.

[Olga (Olga Klimova)]

reinstall cient, you have obsolete Erp.Contracts.BO.Part, probably you did not logoff before upgrade?

[Heide (Heide Warren)]

Hi Olga,
Can you please give me step by step directions for the re-install of the client? I believe that I logged off of Epicor Live and Epicor Pilot. We still use Epicor classic display and I just closed the window with the X in the upper right corner. I know of no way to “log off” on the classic display, other than the red X.

When I did the re-install of Epicor Live and Pilot, in Epicor Live I can open the Part, Part Tracker, and Part Transaction History screen but in Epicor Pilot I have the errors. I completed the re-install all at the same time.
Thank you for the quick response,
Heide

[Olga (Olga Klimova)]

I don’t have the steps. In your case, you should start from empty client folder - delete it or rename for reference. Probably copy from the working machine and check if that will resolve the issue with BPM references you have.

[Heide (Heide Warren)]

Hi Olga,
The process that I used in the past was to un-install Epicor and then copy the client files from the working computer to my computer. One step that we forgot was to delete all files on the C:\ProgramData\Epicor. When I reinstalled Epicor this time, I used https://download.epicorsaas.com.
I have the Part, Part Tracker, and Part Transaction History screens working. But I still have the long error message for the Updatable BAQ. Here is a small part of the error message:

Input mapping expression for ‘Part.Company’ field is invalid: Predefined type ‘System.Void’ is not defined or imported
The type ‘Object’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.

[Olga (Olga Klimova)]

so you are back at the beginning.
what are your local .net installations. What does this command return:

dotnet --info

also, just a guess, do you have nuget packages in %userprofile%.nuget\packages ?

Hi Olga,
Sorry, the nuget information was cut short. Here is the nuget information:

Thank you for the help,

[Olga (Olga Klimova)]

i don’t see anything interesting. What does “dotnet --info” return on working machine?

[klincecum (Kevin Lincecum)]

For anyone searching for solutions, please read this thread:

Problems in BAQ update processing in 2022.2

It looks like other people have ran into this but I can’t see any clear solutions in the other threads. Since upgrading to 2022.2, if I use “Get List” in my updateable BAQ on my computer, I get a slew of errors. If I rdp into the server and run the client there it works fine. The updateable BAQ (in a dashboard) itself works fine. Its just the designer that has this problem. Epicor support says the problem is caused by multiple installs of .net on the workstation and the only solution is to r…

I have a feeling your answer is there. Folder names/versions may be slightly different.

Y’all can thank @Olga

[rkelley792 (Richard Kelley)]

For anyone looking through this thread…I have a solution from Epicor which WORKED!!.

ISSUE
When trying to enable UBAQs/BPMs on certain workstations we get errors but other workstations have no issues.

ERROR
Predefined type ‘System.Void’ is not defined or imported
Predefined type ‘System.String’ is not defined or imported

RESOLUTION
This issue has been identified to be an issue with the .net install.

1. Run the following from a command prompt
   dotnet ––info

Example Output:
.NET runtimes installed:
Microsoft.AspNetCore.App 5.0.17 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 6.0.16 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 5.0.17 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 6.0.9 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 6.0.14 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 6.0.16 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.WindowsDesktop.App 5.0.17 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
Microsoft.WindowsDesktop.App 6.0.16 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

2. The issue has been typically the Microsoft.NETCore.App 6.0.9 folder which is empty and needs to be deleted

[rkelley792 (Richard Kelley)]

@Heide

C:\Program Files\dotnet\shared\Microsoft.NETCore.
App

You needed to delete the folder C:\Program Files\dotnet\shared\Microsoft.NETCore.
App as it is empty and Epicor goes there to find stuff (which isnt there)

[klincecum (Kevin Lincecum)]

@rkelley792

For anyone looking through this thread…I have a solution from Epicor which WORKED!!.

As I said… y’all can thank @Olga

[markdamen]

I’ve marked the first post that contained the solution as answer. Cheers @klincecum.

[klincecum (Kevin Lincecum)]

@markdamen

first post that contained the solution

As long as no one has to deal with this bug, I’m good with whatever

[rkelley792 (Richard Kelley)]

I’m not trying to take credit for anything, but having trawled through this thread I never once came across the solution I was given by Epicor themselves, which was to delete a specific folder. Maybe I missed it, but the fact is the more times a solution is posted, the more chance people will find it. If @Olga posted this already, then I missed it…I just hope anyone with this issue has resolved it now…and moved on like I have.

No worries lol, it’s not in this thread, but the one linked.

Problems in BAQ update processing in 2022.2

Delete 6.0.9 folder

I linked to that thread where people could see the process and solution, in case there was anything slightly different, like if they had a different folder name etc, then they could see how it was figured out.

I don’t care about the solution credit either.

[rkelley792 (Richard Kelley)]

Wish I had found that when I was looking….hate relying on Eoiccare for solutions. However, TBF, on this occasion they were able to resolve my issue, so I got there in the end. Thanks.
