However, upon executing your code, you receive the error: [vuex] unknown mutation type: yields/statePRdate. This indicates that Vuex isn't able to find the mutation you're trying to call.

Solution: Removing Namespacing Confusion

The issue arises from the way Vuex handles namespacing. If your module is not namespaced, you should omit the module name when committing a mutation. So how do you resolve this? Here’s the fix step-by-step:

Step 1: Modify the Commit Statement

You need to adjust the commit statement in your action to remove the namespacing prefix (yields/). Here's how your action should look after the change:

Conclusion

After making these adjustments, you should no longer encounter the [vuex] unknown mutation type: yields/statePRdate error. The key takeaway is to be mindful of the namespacing in your Vuex modules. By ensuring consistent naming and referencing, you can seamlessly manage your Vuex state across modules.
