Problem with extracting residuals
 

Hello, I am trying to get residuals of my case(chtMultiRegionSimpleFoam), Then i got the following error:

[1] --> FOAM FATAL IO ERROR:
[1] keyword type is undefined in dictionary "IOstream.functions.residuals"
[1]

[2] --> FOAM FATAL IO ERROR:
[2] keyword type is undefined in dictionary "IOstream.functions.residuals"
[2]
[2] file: IOstream.functions.residuals from line
[3] keyword type is undefined in dictionary "IOstream.functions.residuals"

Can anyone help with what was going wrong?
