Flow does not reload the text file whenever the text file updated

Dear developer,

I would like to report an issue of Flow, currently I notice it happened on KLWP.

I create a flow that would retrieve and read a text file, then store the file content into a global variable.

However, every time I update the content of the text file, and trigger the flow to reload the text file… the global variable that store the file content is not updated.

Based on my observation, the cause of the issue would be the flow does not reload the file content. The flow did work, the file picking action of the flow worked (I use a “contain” filter for the filename), but the flow just didn’t retrieve the file content.

By the way, to retrieve the file content, I use a Flow’s formula action with this script: $wg(gv(picked_file), raw)$ .
The gv(picked_file) is the global variable for the file path. And for storing the file content, I use this global variable: $gv(file_content)$

Please kindly investigate this issue and provide a solution.

Thank you.
