EXTENSION PUBLICATION - Object reference not set to an instance of an object.
Please include the following with each issue:
1. Describe the bug I have a production environment, to which I make a sandbox copy. In the sandbox environment, I run a customized extension. It currently works fine. The necessary changes are made, it runs, and tests are performed normally. Then, the execution stops, changes are made, and it runs again, and we get this error: Object reference not set to an instance of an object.
Assuming the error could be caused by the code, the latest changes are deleted, leaving the version that did run, and it cannot be published. The same error appears.
Another test is to obtain another sandbox, upload the changes (which initially didn't upload), and it uploads correctly. We try to make more changes, but we can't. The error is always the same.
2. To Reproduce execution, stop execution, re-execute.
- Go to '...'
Note: Because the developers need to copy and paste the code snippet, including a code snippet as a media file (i.e. .gif) is not sufficient.
3. Expected behavior Executions are expected to continue to be published in the sandbox
4. Actual behavior You cannot perform more than 2 executions.
5. Versions:
- AL Language:
- Visual Studio Code: 16.0.1523709
- Business Central: 26.1
- List of Visual Studio Code extensions that you have installed:
- Version: 1.100.3 (user setup) Commit: 258e40fedc6cb8edf399a463ce3a9d32e7e1f6f3 Date: 2025-06-02T13:30:54.273Z Electron: 34.5.1 ElectronBuildId: 11369351 Chromium: 132.0.6834.210 Node.js: 20.19.0 V8: 13.2.152.41-electron.0 OS: Windows_NT x64 10.0.22631

I had a similar error in my docker. The docker was unsuable after I tried to publish my app. The error could be related to the new multiline-text syntax, since the error occured after I switched to runtime to 15.0.

THE ERROR PERSISTS FOR NOW, I FOUND THAT RESTARTING THE ENVIRONMENT ALLOWS PUBLISHING. THE ERROR PASSES AFTER A FEW EXECUTIONS, SO I RESTART THE ENVIRONMENT AND CONTINUE.
Issue has been fixed. Fix is available on all platform builds for v27 and it is also available on v26 in platform builds 26.0.37867.0 or later.
