I am currently designing an automation process and wanted to get some feedback on my architectural approach. . I am following the Dispatcher-Performer pattern and have already built the logic for both components. I’m a beginner to this. Dispatcher: Fetches source data from an API and uploads items…

Hi @aparna.dhanesh , You’re on the right track, this is a common design question. In practice, the recommended approach is to keep Dispatcher and Performer as two separate projects.

Thank you for the feedback @iampnkz

Sure, Currently I’m working on it, I have separated the flow. Now I’m getting the below error . [image]

Hi @aparna.dhanesh , Can you please check if you are using a stable version of the Excel activities package (UiPath.Excel.Activities)? Avoid using preview versions. Also, try using another Excel file to ensure that the issue is not file-specific. Thanks!

Thank you for the suggestion. I have confirmed that I am using stable version 2.24.4 of the UiPath.Excel.Activities package with a Strict runtime rule. This version is working perfectly in my Dispatcher project, but failing in the Performer.

Hi @aparna.dhanesh , Can you try uninstalling the current Excel Activities package and installing a slightly lower stable version? Also, try debugging the project and check whether the issue is occurring for a particular sheet. Thanks

Hi @iampnkz , I have already uninstalled the packages and reinstalled them multiple times. I also performed a ‘Nuclear Clean’ by deleting the entire NuGet cache and the .local folders, but the error remains. The crash happens at the very start of the Read Range activity.

@aparna.dhanesh , Can you mark it as a solution so that it can help others. Thanks
