Cirrostratusgoogle 2fa irule error
I'm struggling with this error when doing "load sys config verify
[use curly braces to avoid double substitution]
full error message
/Common/Google_Token:131: warning: [use curly braces to avoid double substitution][(0x{[string range ${token} ${offset} [expr {${offset} + 7}]]}]
The irule line in original code was
set ga_code [expr (0x[string range $token $offset [expr $offset + 7]] & 0x7FFFFFFF) % 1000000]
And I changed it to
set ga_code [expr (0x[string range ${token} ${offset} [expr {${offset} + 7}]] & 0x7FFFFFFF) % 1000000]
I'm able to connect to APM and passing the token , it is working fine there, but this cannot get rid of this error message
Any one can help with the correct syntax ?

Dear Abed,
checking the F5 knowledgebase article, I would interpret the correct syntax as follows:
set ga_code [expr {0x[string range $token $offset [expr {$offset + 7}]] & 0x7FFFFFFF} % 1000000]But I don't have tested it right now, so please give it a try.
Thank you!
Regards,
Stefan 🙂
Abed_AL-RI actually tried this
The F5 accept the irule
and the error disappears
but the APM connection is not working anymore
when I try to connect , I pass the username / password , then I type the OTP , and when I click 'next' the APM resets the connection and start over from the beginning
so it stop resuming to establishing the connection
