MVPI would try to verify in first place, whether this message is sent by the BIG-IP at all. I would be highly surprised.
My approach to analyse this issue would be to access the application:
a) direct, bypassing the BIG-IP
b) via BIG-IP without ANY ASM features assigned to the VS
c) via BIG-IP with ASM features enabled
Use Developer Tools in Browser for a, b and c. Compare. Look for error messages, 404, etc.
Use tcpdump on F5 for b and c. Use the p flag to capture client- and server-side. Compare.
My first guess would be, that maybe something is in the application that is preventing the JavaScript from beeing executed properly when the application is accessed via a reverse proxy.
neeeewbiethank you
Yes I already tried it
client does not received this message when disablr asm policy
even I take a pcap, it is not display which asm function sent message

Then take a look at: K64034374: BIG-IP ASM unable to find Support ID in Event Logs when blocking page shows "Please enable JavaScript to view the page content"
Pay attention to "Recommended Actions
It is recommended that the user enable JavaScript for their browser client and disable any plug-ins which disable JavaScript."If this doesn't help... I am out of ideas 🙂
