Hi Tatu,
Thank you very much for your response :
We can neglect the Gson Parsing
the issue after debugging it exactly after calling readValue as shown here :
HashMap<String, Object> obj = mapper.readValue(responseBuffer.toString(),
typeRef);
for example, let's take this Key,Value from the original File :
Conditions:
ProvidedAdminEmail: !Not [!Equals [!Ref AdminEmail, '']]
ProvidedTargetGroups: !Not [!Equals [!Ref GatewaysTargetGroups, '']]
EnableCloudWatch: !Equals [!Ref CloudWatch, true]
CreateELB: !Not [!Equals [!Ref ELBType, none]]
After Debugging, i found that ObjectMapper using YamlParser change the text
that starting with ! as :
Conditions={ProvidedAdminEmail=[[AdminEmail, ]],
ProvidedTargetGroups=[[GatewaysTargetGroups, ]],
EnableCloudWatch=[CloudWatch, true], CreateELB=[[ELBType, none]]}
And i stopped the debugger before continue with Gson parsing, so the issue
100% with the YamlParser used by Deserializer
Yesterday I debugged the YamlParser and found it is simply skipping the
String that start with ! (maybe i'm wrong, you are expert than me)
i wrote here :
https://stackoverflow.com/questions/61784803/jackson-yaml-parser-deleted-special-characters
After Debugging, i found that the issue with : Object value =
deserialize(p, ctxt); Inside Class : UntypedObjectDeserializer when
deserialize try to find the value, i see that the Parser has current token
: !Ref but the YAMLParser advanced to the next token and neglect it in a
strange way I'm talking about this line Number 648 JsonToken t =
p.nextToken(); Inside deserialize Function I need here some one expert with
YamlParser to find where is the issue
i believe you are one of the most active and intelligent contributor to
this Project and i sure you will find where is exactly the issue
