Execution failed: stdout maxBuffer length exceeded on GitHub Actions (Windows Server 2025)

[muzanella11]

Description:

When running a workflow on GitHub Actions with the Windows Server 2025 runner, the build process fails with the following error:

Steps to Reproduce:

1. Use the windows-2025 runner in a GitHub Actions workflow.
2. Run a build/compile job (e.g., npm run build or another command).
3. The process produces a large amount of output logs.
4. The job fails with stdout maxBuffer length exceeded.

Expected Behavior:

The workflow should complete successfully even if the build produces a large amount of log output.

Actual Behavior:

The build stops with stdout maxBuffer length exceeded before completing.

Possible Solutions (Optional):

• If using child_process.exec, increase the maxBuffer option.
• Consider switching to spawn to handle logs as a stream instead of a buffer.
• Reduce verbosity of log output to avoid hitting the buffer limit.

Do you know if this happens when Chocolatey runs or after Inno Setup itself is called? I'm going to increase the buffer size, but I need to know where it is. I could do it for both, but I feel like it's best to only do it for wherever it's needed.

Sorry for the late response. I'm not entirely sure at which step the process breaks, as I've since switched to running Chocolatey to set up Inno Setup manually and then compiling the ISS file to an EXE. From what I recall, it seems that the process failed after Inno Setup was called.

We have also started hitting this today with Tauon.

I sent in a PR, meanwhile you can use C0rn3j/Inno-Setup-Action@v1.2.8 instead.
