Regsub function not working in Action Message

[gert.derouck]

Hi,

In v5.2 regsub functions don't work any more...

My message looks like:

Problem started at {EVENT.TIME} on {EVENT.DATE}
Problem name: {EVENT.NAME}

Item Name: {ITEM.NAME}
Item Key: {ITEM.KEY}
Item Last Value: {EVENT.OPDATA}
Tags: {EVENT.TAGS}

ZMM Component: {{EVENT.NAME}.regsub("^.*[(.*)])", "\1")}
ZMM Severity: {EVENT.SEVERITY}
ZMM Problem ID: {EVENT.ID}

{TRIGGER.URL}

The resulting message looks like this:

Problem started at 14:45:27 on 2021.09.21
Problem name: Solarwinds P1 [JACAIBNS01] - Node is down

Item Name: Solarwinds Trap create and close

<snip>

ZMM Component: {Solarwinds P1 [JACAIBNS01] - Node is down.regsub("^.*[(.*)])", "\1")}
ZMM Severity: Disaster
ZMM Problem ID: 67274

The regsub function is not executed but included as plain text...?!

This worked fine in v4.2.


Any idea on how to fix this?
