If you try to find out what week today is, a fail occurs

I don’t know which value was entered incorrectly. Any help please?

${week_no}	Google.Get Week No	2023	1	6

ValueError: Unknown format code ‘d’ for object of type ‘str’

You really should have given us more context!

What Library is that Google ?

But just from the error message I would try:

${week_no}=     Google.Get Week No    ${2023}    ${1}    ${6}
