caught: undefined local variable or method `path' and caught: Index -1 out of bounds errors with logstash version 8.19 and latest azure blob plugin

[ChandrikaMuniyappa]

I am trying to setup logstash top read the content of azure blob storage account and write the logs into elasticsearch.
Here are specifications:
VM: Ubuntu 24.04
Logstash Version: 8.19.9
Azure blob storage plugin Version: 0.12.10

Version Details:
ctuser@elasticlogstash:$ /usr/share/logstash/bin/logstash --version
Using bundled JDK: /usr/share/logstash/jdk
logstash 8.19.9
ctuser@elasticlogstash:$ /usr/share/logstash/bin/logstash-plugin list --verbose azure_blob_storage
Using bundled JDK: /usr/share/logstash/jdk
logstash-input-azure_blob_storage (0.12.10)
ctuser@elasticlogstash:~$

Input content of logstash config file
input {
azure_blob_storage {
storageaccount => "saccount1"
access_key => "Valid storageaccountkey"
container => "sacontainer"
prefix => "*"
registry_path => "/var/lib/logstash/local_registry.dat"

# Point registry to a clean local file to avoid the 404 error
interval => 300
codec => "plain"   
# We removed 'registry_create_policy' to let the plugin 
# initialize naturally without forcing a 'start_over' state

}
}

Upon running the logstash service, it fails with below error:
