I am getting an "This Cucumber Expression has a problem" error

[rref1943]

I am attempting to migrate from SpecFlow to Reqnroll. I replaced the VS extension for SpecFlow with Reqnroll and I changed the SpecFlow related nugets to Reqnroll along with the references to them in the *.cs files. After migrating I had to escape all '/' characters in the Given, When, Then statements in the step definitions.

In one of my feature files I have the following statement:

Then I should see the Order Split title show 'Items Selected: 1 / <total number of items on order> | (Order Split)'

And in the step definition for that:

[Then(@"I should see the Order Split title show 'Items Selected: 1 \/ <total number of items on order> \| \((Order Split|stop move)\)'")]
public void ThenIShouldSeeTheSplitOrderLabelShow(string numOfItemsSelected, string splitOrderOrStopMove)

When I build the project though I get the following error:

Severity Code Description Project File Line Suppression State Details
Error This Cucumber Expression has a problem at column 97:

I should see the Order Split title show 'Items Selected: 1 / | ((Order Split|stop move))'
^
Only the characters '{', '}', '(', ')', '', '/' and whitespace can be escaped.
If you did mean to use an '' you can use '\' to escape it

(The caret symbol is actually below the 't' in "/ <total number")

With SpecFlow I did not face this issue. Can anyone help me understand what's happening and resolve this please?

In case your regular expression is wrongly detected as cucumber expression, you can always force to use regular expression by specifying the regex start/end markers (^/$).
