Spring Cloud Config returns an empty string instead of an empty array #2746
Description
Describe the bug
After upgrading to the latest version of Spring Cloud Config, I encountered an issue where the cloud-config service returns an empty string ("") instead of an empty array ([]).
<spring-cloud.version>2024.0.0</spring-cloud.version>
Sample
Example:
config.yaml
network:
urls: []
I expect to receive the following object:
{
"network":{
"urls":[]
}
}
However, I receive this instead:
{
"network":{
"urls":""
}
}
I noticed a similar issue in the past, which might be related to this problem as well.
#1572
Could you please investigate the cause of this issue as soon as possible?
Thanks in advance!
