Error: Couldn't find valid bootstrap(s): [/var/task/bootstrap /opt/bootstrap] using bref/bref 2.1.0

Description:

i have the error Error: Couldn't find valid bootstrap(s): [/var/task/bootstrap /opt/bootstrap] on my lambda after sls deploy --stage=#env# -- function=#function_name#

How to reproduce:

1. deploy you stack with multiple function sls deploy --stage=#env#
2. deploy only one fonction with sls deploy --stage=#env# -- function=#function_name#
3. run the function and see the error

Have you added the Lambda layer (or use the proper PHP runtime) in serverless.yml?

Could you double check what gets deployed in the console?

It looks like someone is off, deploying a single function is something widely used across bref users (including me), either something broke very recently in Serverless Framework or something is wrong on your side. Can you reproduce with an empty project?

[cedric-r-mycelium]

Yes i have runtime: php-82

I have try to reproduce on empty project but i don't have the probleme on my try. i will search more deep

I ran into this. It was related to the fact my runtime was declared globally. Moving the runtime to the function declaration fixed the issue.

When looking in the console, it was not deployed with the php-82 layer, just the extension layer.

oh that's interesting, if you have a reproducible example that would be great, that way we can identify the root problem! (maybe a bug in the JS serverless plugin)

was it with a specific runtime? (console maybe?)

[t-richard]

Reproduced with a config like this

service: test

provider:
    name: aws
    region: eu-west-1
    stage: dev
    runtime: php-82

plugins:
  - ./vendor/bref/bref
  - ./vendor/bref/extra-php-extensions

functions:
    test:
        handler: index.php
        layers:
            - ${bref-extra:imagick-php-82}

It actually is a bug (or at least behaviour) inside the serverless framework.

When defining the runtime globally, bref sets the php-82 layer globally

bref/index.js

Lines 202 to 209 in 3a4a335

	if (this.runtimes.includes(config.provider.runtime || '')) {
	config.provider.layers = includeBrefLayers(
	config.provider.runtime,
	config.provider.layers || [], // make sure it's an array
	isArmGlobally,
	);
	config.provider.runtime = 'provided.al2';
	}

Those global layers are ignored by the serverless framework on deploy if you have layers defined at the function level.

See : serverless/serverless#11063

Let's go 🙌

Two Bref bugs fixed today, that's awesome!
