Error thrown when using a Step from a Definition with an optional parameter

[nextlevelbeard]

👓 What did you see?

Error is thrown when a valid step is described in a Scenario:

[Error - 6:01:37 PM] Request textDocument/semanticTokens/full failed.
  Message: Request textDocument/semanticTokens/full failed with message: Incomplete group: {"children":[]}
  Code: -32603

✅ What did you expect to see?

No errors.

📦 Which tool/library version are you using?

Extension version 1.3.0

🔬 How could we reproduce it?

With the following valid Step Definition:

Then(/I should( not)? be on the map/i, async (not) => { })

and the Step I should be on the Map :

Feature: Bug Report

  Scenario: User reports a bug
    Then I should be on the Map

📚 Any additional context?

The step definition is valid and made to support a positive and negative case.

Both I should be on the Map and I should not be on the Map are valid steps.

However, the error is only thrown with the positive case: I should be on the Map

Unfortunately I've stumbled across this error today with the same scenario described by @nextlevelbeard

[Error - 3:13:38 PM] Request textDocument/semanticTokens/full failed.
  Message: Request textDocument/semanticTokens/full failed with message: Incomplete group: {"children":[]}
