Hi, My second guess :) Check this https://github.com/OpenSIPS/opensips/blob/master/modules/python/handler.py <https://github.com/OpenSIPS/opensips/blob/master/modules/python/handler.py>
Differs from your version… Can these differences cause the failure? The __init__ located inside class And the mod_init located last in the script (does the order count for anything in python?) Also called handler function always returns 1 not the init Tomi On 16.

And then only did I put it (the class) to use in opensips.. Had there been an issue, python3 would have kicked and scream which it did not. No issue with the regexp.

This collides with Python’s usage of the same character for the same purpose in string literals; for example, to match a literal backslash, one might have to write '\\\\' as the pattern string, because the regular expression must be \\, and each backslash must be expressed as \\ inside a regular Python string literal. Also, please note that any invalid escape sequences in Python’s usage of the backslash in string literals now generate a DeprecationWarning <https://docs.python.org/3/library/exceptions.html#DeprecationWarning> and in the future this will become a SyntaxError <https://docs.python.org/3/library/exceptions.html#SyntaxError>. This behaviour will happen even if it is a valid escape sequence for a regular expression. The solution is to use Python’s raw string notation for regular expression patterns; backslashes are not handled in any special way in a string literal prefixed with 'r'. So r"\n" is a two-character string containing '\' and 'n', while "\n"is a one-character string containing a newline. Tomi On 16.

If i did a print (LM_ERR)a static string in the get_rn() before the line that calls compile(), i noticed that it does print out. And if i tried to print a static string right after the compile() call, it doesn't print and it calls TypeError. That's why i suspect something is wrong bit can't tell exactly what....

It looks like you are trying to do a print on a Class definition.

I have a script which parses a number in a string (r'.*rn=\+6114(\d{2})'). Script is as follows: ---------- start --------------- #!/usr/bin/python3 import re; import pprint; class test: def get_rn(): rnRegExp = rnRegExp = re.compile(r'.*rn=\+6114(\d{2})'); doit = rnRegExp.match( str("sip:+61386947785;npdi;rn=+611...@tipt.ns.zippi.vocus.com <mailto:611...@tipt.ns.zippi.vocus.com>;user=phone")); if doit: pp = pprint.PrettyPrinter(indent=4); return doit.group(1); else: return None; result = test.get_rn(); if result is None: print("Got no match\n"); else: print("Result is " + result); ----------- end -------------- In my opensips setup, I have the function above looking like this: ---- start-------- from OpenSIPS import LM_ERR import re; import pprint; def mod_init(): print("In mod_init, SIP MSG is : "); pp = pprint.PrettyPrinter(indent=4) pp.pprint(SIPMsg); return SIPMsg(); def __init__(): return 1; import re; import pprint; class SIPMsg: def child_init(self, rank): return 0 def get_rn(self, msg, raw_enum_result): try: get_rn = re.compile(r'.*rn=\+6114(\d{2})'); rn = get_rn.match(str(raw_enum_result)); return rn.group(1); except AttributeError: # Invalid input string LM_ERR(" attribute ERRor" ); return ''; except TypeError: # Invalid input string LM_ERR(" Type Error" ); return ''; else: LM_ERR(" general ERRor" ); return ''; ----- end ------ In my opensips config, I call the get_rn() function via python_exec() as below. $var(rn_code)=python_exec("get_rn", $var(raw_string)); I'm facing an issue here because when I run the script by itself in a command line, it works. No "Error: Text Type" but when my opensips run, it keeps hitting a TypeError. I have even explicitly fed the " rn = get_rn.match(str(raw_enum_result));" with an explicit string (ie. I dont send use the value passed in from the argument BUT instead, just feed it an explicit string value) and yet the same issue occurs. Does processing control belong directly to python3 when we call python_exec() or is there something funny going on here?
