> The *ExtractText processor* is unexpectedly adding matched values *three
> times* when processing FlowFiles with a regex pattern. Even with a simple
> pattern like {{{}(?s)(.*){}}}, the extracted value is stored *exactly three
> times* in the FlowFile attributes.
> h4. *Steps to Reproduce*
> # Create an *ExtractText* processor in NiFi.
> # Set the *Enable repeating capture group* property to {{{}true{}}}.
> # Use a simple regex pattern, such as {{{}(?s)(.*){}}}.
> # Process a FlowFile containing any text.
> # Observe the extracted attributes.
> h4. *Expected Behavior*
> * The extracted text should be stored *once* in the attributes when matching
> the entire content.
> h4. *Actual Behavior*
> * The extracted text is added {*}three times{*}, leading to duplicate
> entries.
