We have a development environment that has many instances of Acumatica installed and in the past week or two publishing from the customization project editor no longer works.  The log window at the bottom opens and nothing is logged.  There is a warning in the windows application log for ASP.NET.4.0.30319.0.  I have included the details at the bottom.  This is happening for all 20+ versions of Acumatica installed in any application pool. 

There is a workaround to update any changes through the editor, but then publish from the customization projects list screen (SM204505).

Thanks,

Kurt Bauer

It’s a known issue currently under investigation.

As a workaround for self-hosted Acumatica instance. Modify web server file ‘Web.Config’ at the root of your Acumatica instance folder.

 

Add this key in appSettings section:

<appSettings>

    ...

    <add key="aspnet:DisableAppPathModifier" value="false" />
</appSettings>

 

For instance hosted on Acumatica SaaS service please open a support case with Acumatica.

The issue occurs with .Net version 4.8.4250. It works up to version 4.8.3752 without this workaround.

Hughes, thank you a lot for providing a workaround!

We issued the knowledge base article related to the issue: Known issue: After an upgrade to .NET Framework version 4.8.4250, users were unable to publish a customization project from the Customization Project Editor

The same root cause is bringing another issue affecting users in the system, for more info refer to the Known issue: After an upgrade to .NET Framework version 4.8.4250, users could face an issue when the default data was not specified in a pop-up window

The bug is fixed in those versions which will be released soon:

  • 2019 R1 Update 22
  • 2019 R2 Update 15
  • 2020 R1 Update 13
  • 2020 R2 Update 3
  • 2021 R1 Beta

For your information, the exact root cause has been determined:

If Microsoft .NET Framework 4.8.4250 was used on Acumatica web server, users are unable to publish a customization project from the Customization Project Editor .

Hello, 

I am new with this software.  How do i fix this issue?

<appSettings>

    ...

    <add key="aspnet:DisableAppPathModifier" value="false" />
</appSettings>

i cant find this in the config file. Please help.

Regards

The appSettings element should be there. You need to insert the DisableAppPathModifier line in the text file.
