the pulumi cli executes your code via ts-node by default. Is that also how you're configuring your automation api program? This could explain the discrepancy.

Would be worth logging out the values of saConfiguration in both cases just to be sure.

I'm guessing that's the reason - I switched from ts-node to tsc build &amp; run to get it working more natively in pipelines.. but it was technically correct- common was not set on saConfiguraton (using the same stack config on both cases, that's the point) and should technically have errored out both times :slightly_smiling_face:

now on to the next issue - but I'm hoping that might be a tsc vs ts-node thing as well:
previewing stack

Error: The Pulumi runtime detected that 904 promises were still active

at the time that the process exited.

that doesn't even occur when i do tsc build &amp; run locally.. heh.

nah, actually - everything is weird everywhere now. I'm going to have to bow my head in shame until I pinpoint exactly what's going weird.

```// end of ts-node <http://stack.info|stack.info>() - exactly the same as for tsc version.

given the exact same stack config - somehow automation wants me to update 2 and pulumi cli has 12 unchanged. I'll dig a bit morte

Yeah - you're right - there's -definetely- something weird about how automation is reading stack config.

When running the debugger, it complained about my pulumi.requireObject("&lt;configname&gt;") stuff. it looks to me like it's somehow trying to set default values for at least /some/ things..
