Longer secret string throws error

[Steffen911]

What happened:
I use an .actrc file to provide the target docker image and a secret that corresponds to an inlined maven settings.xml file.
Now, when I run act I get Error: accepts at most 1 arg(s), received 64.

My .actrc:

-P ubuntu-18.04=nektos/act-environments-ubuntu:18.04
-s SETTINGS_XML='<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd"> <servers> <server> <id>backend-s3-release-repo</id> <username><USERNAME></username> <password><PASSWORD></password> </server> <server> <id>backend-s3-snapshot-repo</id> <username><USERNAME></username> <password><PASSWORD></password> </server> </servers> </settings>'

I tried to assign the value with single quotes, double quotes (with escaping the inner quotes) and without any quotes add all. The error is always the same.

When I pass the secret via the environment everything works fine and change the .actrc file to

-P ubuntu-18.04=nektos/act-environments-ubuntu:18.04
-s SETTINGS_XML

everything works as expected.

What I expect to happen:
It should run the workflow with the given settings.xml as the secret.
