Getting Function `browsershot` not found in environment `staging` but fine locally

[jimhill]

Problem

The issue occurs for me using wnx/sidecar-browsershot (which I know isn't this package), but having run through as much of the code as I can, it feels like this is a Sidecar thing.

Everything runs perfectly well in my local environment, however as soon as I run from our AWS staging environment I get the following error when trying to call it:

staging.ERROR: Function `browsershot` not found in environment `staging`.
It may exist other environments, you may need to overwrite the environment while deploying to `staging`.

The lambdas are there with the correct names, they have the exact same code in too.

Any thoughts or any more I can do to help diagnose the issue?

So I have managed to isolate the problem, and work around it. Just haven't dug in enough to understand why it's a problem and to see if it's a config issue in our staging environment.

The issue is in the nameWithPrefix() method in Hammerstone\Sidecar\LambdaFunction.

https://github.com/hammerstonedev/sidecar/blob/5d1e03bd023962287aab61870a152f9d150c83c0/src/LambdaFunction.php#L120C37-L121C6

Our APP_NAME env var is set to something like AppName Staging.

Using artisan sidecar:deploy --activate , the deployed lambda then has a name like sc-appname-staging-browsershot.

But when executed, the $prefix-$name value looks in the method is sc-appname-staging-staging-browsershot

---

💡 Currently the workaround for now has been to set an env var for SIDECAR_APP_NAME to just AppName.
