I've successfully tested Variable Registries in the *Replacement Value*
field, but I still can't get it to work in the *Search Value* field
with *Replacement
Strategy* as Literal Replace and *Evaluation* as Entire Text.
Here is something really weird. I created a GenerateFlowFile and used
my ${tier1.linux} variable in the *Custom Text* field. Creates the flow
file as expected, with the expected text. But then in my ReplaceText's *Search
Value* field I use my ${tier1.linux} variable with *Replacement* being
anything, and it *does not* successfully search and replace the text.
Thoughts?
*GenerateFlowFile Values*
File Size: 0B
Batch Size: 1
Data Format: Text (granted, I'm using JSON in my official version, but it
should still work)
Unique FlowFiles: false
Custom Text: ${tier1.linux}
Character Set: UTF-8
Mime Type: No value set
*ReplaceText Values*
Search Value: ${tier1.linux}
Replacement Value: hello world
Character Set: UTF-8
Max Buff Size: 1MB (way more than I need)
Replacement Strat: Literal Replace
Evaluation Mode: Entire Text
Line-b-Line: All
