Run Apps .yxwz with error "Object reference not set to an instance of an object" in 2025

[TTMCarrieCai]

Run Apps .yxwz  file is good in Alteryx version 2024, but after install verison 2025.1, run the Apps .yxwz  file with error "Object reference not set to an instance of an object".

How to fix it in my computer?

By any chance, you have Copilot installed?

Hey --- so there a lot of things which can create this error - but the usual reason is that some parameter isn't being passed to a .NET package or something. Can you:

1) open the .yxwz in Alteryx --- not via file explorer.

2) look at any interface tools and their mappings --- did any templates/files get reset?

3) run once via regular run.

4) save.

5) run via wand.

that's what I'd try in terms of troubleshooting.

I haven't installed Copilot.

I uninstalled Alteryx 2024, delete the full data folder, but after install Alteryx 2025, still can't run yxwz file with same error "Object reference not set to an instance of an object".

After uninstall 2025, reinstall 2024, can  run yxwz in 2024.

How can I update to 2025?

Tools Removed from Designer Installation

These tools are no longer automatically installed with Designer:

• Insights (deprecated tool, the associated One Tool Example has also been removed)

• Marketo Append, Input, and Output: These tools are no longer automatically installed with Designer but are still available for download via Alteryx Marketplace.

• Salesforce Input and Output Macros (deprecated): Alternatives (supported connectors) are available via Alteryx Marketplace.

• Twitter Search (deprecated)

Which one are you using?

Hello! Could this be python related? Starting at Alteryx 2024.1 there was a major python upgrade, and I see you are already on 2024.1 so there shouldnt be any connector issues up to 2025.1, but i would still double check this.

[TTMCarrieCai]

I didn't use this tools.

My computer has installed Python, verision 3.13.0.

Is it due to the Python version?

[jensroy]

Not likely, Alteryx comes with its own embedded version of Python so your existing python enviroments will not interfare.

Hey - let's start by you sharing your workflow -or at least screenshots of your workflow - so we can see the tools --- the most likely reasons you are seeing this are corrupted .yxwz file (copy/paste new file/try again) or one of the tools is different in 2024 vs 2025 --- either it requires a different parameter, it does not exist in 2025 or the config is drastically different in 2025 --- which tool --- can't really tell without seeing your workflow.

[TTMCarrieCai]

All yxwz file is failure under 2025, while good in 2024.

We have 2025 in another computer, the yxwz file is good under 2025.

Just a specific computer has the issue.
