How to use multiple keys in PLUGIN_BUILD_ARGS_FROM_ENV, using secrets

[Manuel_Gonzalez_US]

I’m trying to use multiple keys with PLUGIN_BUILD_ARGS_FROM_ENV, I’m trying this
envFrom:
- sourceName: awscredentials
sourceKey: AWS_ACCESS_KEY
- sourceName: awscredentials
sourceKey: AWS_SECRET_KEY
env:
PLUGIN_BUILD_ARGS_FROM_ENV: AWS_ACCESS_KEY,AWS_SECRET_KEY

But it seems like it does not work, since the pipeline never ends, stuck in “setting up executors” and never ends, if I only put one key, the pipeline works… of course, the build for my image fails since it needs both keys.

Any ideas?
Thanks in advance
