Certain complex accessControl policies may not properly grant authorization #771
Description
accessControl policies for MQTT will not support the # or + MQTT wildcard substitutions in the same policy including a normal * wildcard (the MQTT wildcards can still be used if the policy does not include a ). accessControl policies will not support the ${}, ${?}, and ${$} escape sequences either. They also do not support recipe variable interpolations in policies due to Greengrass Lite not supporting recipe variable interpolation in configuration yet and accessControl policies are part of the component configuration.
Workaround: Use simpler authorization policies that do not make use of these features, referencing the docs here: https://docs.aws.amazon.com/greengrass/v2/developerguide/interprocess-communication.html
