@J0sh ,

 

If you use a ReplaceText with the following settings it will clean up the garbage in your flowfiles:

Search Value:      (?s)(^|(\})<br>).*?(\n).*?(<br>(\{)|$)
Replacement Value: $2$3$5

araujo_0-1650577447677.png

 

This file, though, has not 1 JSON, but 8 different JSON fragments. So the resulting flowfile will still have 8 lines, each with a valid JSON. You must use a SplitText process to separate those into 8 different flowfiles before applying the EvaluateJSONPath.

 

Cheers,

André

any support 
Im new 
should I use 
RouteonContent or Attribute 
How do I define Attributes 

Master Collaborator

@J0sh 

 

You can use a ReplaceText processor with the following properties:

Search Value:      (?s)^.*?(\{".*\}).*$
Replacement Value: $1

Thank you for the Response 
I tried this processor and connected to EvaulateJSONPath & It gave an error msg:
This is not a valid JSON Content

Can you provide me with the entire contents of your flow file?
