Invalid field path with Firestore

I have an error with Firestore today, because I'm trying to fetch a path with a forbidden character. 

REF_ROOT.document(currentUser.uid).collection("records").whereField(workoutName, isEqualTo: "Open 16.5 / 14.5").getDocuments

Is it possible to add a backslash or anything before the slash (or any forbidden character in fact), in order to proceed this request?

This is my log:

Invalid field path (Open 16.5 / 14.5). Paths must not contain '~', '*', '/', '[', or ']'
firebase::firestore::util::ObjcThrowHandler(firebase::firestore::util::ExceptionType, char const*, char const*, int, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)

Don't confuse paths with the field data they point to.

"Open 16.5 / 14.5" is a perfectly legitimate value to store in a Firestore field.

Your query is this

REF_ROOT.document(currentUser.uid).collection("records")
                                  .whereField(workoutName, isEqualTo: "Open 16.5 / 14.5")
                                  .getDocuments

Which tells me that currentUser.uid or the workoutName contains the invalid character, and it's most likely workoutName.

Try printing that out before the call to see what prints in console.

print(workoutName) //probably prints this: Open 16.5 / 14.5
REF_ROOT.document(currentUser.uid).collection("records")
                                  .whereField(workoutName, isEqualTo: "Open 16.5 / 14.5")
                                  .getDocuments
