 I am getting the following error

"Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \ )"  

I don't know how to handle that error.

Hello,

When you get some compile errors, please check your "Code" tab in your job. There will be your compile error highlighted in red line.

Best regards

One of your components contains a string with a \ character. That is used as an escape character in Java strings. If you want a literal \ in your string, you need to escape the escape character and type \\

As it is said above escape the escape character. i had the same error but got it resolved.

e,g: "C:\Users\tr5677\Desktop" if this is your output path.

change it to 

"C:\\Users\\tr5677\\Desktop".

error was gone after this.

Team,

I'm new to Talend and struggling with a similar error. Hope someone would help me. I'm setting an Implicit tContext for a job. The environment is windows.

When I run the job, I get theerror message (see error.png.)

I then changed the path to  "C:\\TCTC_Course_Data\\Input\\tContextLoad_dev_conn.csv" and still get the below error.

Exception in component Implicit_Context_Regex (Implicit_Context_Load)
