WSO2IS - deployment.toml - Invalid escape sequence - wso2

Question

I'm facing some problems converting user-mgt.xml file from wso2is:5.8.0 to wso2is:5.10.0 version. I have some configurations in user-mgt.xml to primary user store using ldap and now when I use deployment.toml I can't start the server.
docker container log:

deployment.toml from newer version 5.10.0:
[user_store.properties]
...
UsernameJavaRegEx = "^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$"
UsernameJavaScriptRegEx = "^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$"
UsernameJavaRegExViolationErrorMsg = "Username pattern policy violated"
PasswordJavaRegEx = "^[\S]{5,30}$"
PasswordJavaScriptRegEx = "^[\S]{5,30}$"
PasswordJavaRegExViolationErrorMsg = "Password length should be within 5 to 30 characters"
RolenameJavaRegEx = "[a-zA-Z0-9._\-|//]{3,30}$"
RolenameJavaScriptRegEx = "^[\S]{3,30}$"
....
How can I fix this problem?

Answer 1

In order to use \ in the configs, you need to use the escape character(\). (eg: ^[\\S]{5,30}$)
Try out these.
[user_store]
username_java_regex = "^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,4}$"
username_java_script_regex = "^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,4}$"
username_java_regex_violation_error_msg = "Username pattern policy violated"
password_java_regex = "^[\\S]{5,30}$"
password_java_script_regex = "^[\\S]{5,30}$"
password_java_regrx_violation_error_msg = "Password length should be within 5 to 30 characters"
rolename_java_regex = "[a-zA-Z0-9._\\-|//]{3,30}$"
rolename_java_script_regex = "^[\\S]{3,30}$"
