regexp_extract Error when put { in pattern

[William_Scardua]

HI guys,

I tried to use the regex_extract but when I put { in pattern I received error

display(
    df_containerlog.withColumn('reg', regexp_extract(col('LogEntry'), "((^.*))({'data':)", 1))
)

have any idea

Thank you

what do you want to achieve with the curly brace?  It is a regex character so you can't just add it.
If you want to match on it, you should escape it and perhaps even put it within the quotes.
You can always test your regex in online tools like regex101 or regexr or ... very handy

Hello William,

You have to escape the { as it is a special char in case of regex.

"((^.*))(\{'data':)"
