Issue with custom activity related to mongoDB persistence provider

[chiragp9]

I created a custom activity as per a below link, but I am getting an error as attached in screenshot when I call that activity from postman. https://v3.elsaworkflows.io/docs/extensibility/custom-activities

Error Stack: MongoDB.Driver.MongoBulkWriteException1[Elsa.Workflows.Runtime.Entities.WorkflowExecutionLogRecord]: A bulk write operation resulted in one or more errors.

To assist you with the error you're encountering with your custom activity in Elsa Studio, I would need to see the specific error message that is displayed when you drop the activity into the studio. The screenshot you mentioned seems to be missing or not properly linked, as I cannot view it.

However, based on the code snippet you provided for your custom activity, the code appears to be correctly structured according to the documentation for creating custom activities in Elsa 3.0. If you're following the documentation correctly but still encountering an error, it could be due to several reasons such as:

1. An issue with the Elsa Studio setup or configuration.
2. A mismatch between the Elsa version you're using and the version covered in the documentation.
3. A missing or incorrect registration of the custom activity in your application's startup configuration.
4. A potential bug in Elsa Studio or the Elsa framework itself.

To further diagnose the issue, please provide the following information:

• The exact error message you're seeing in Elsa Studio.
• The version of Elsa you're using.
• The relevant parts of your Program.cs or Startup.cs file where you register your custom activity.

Once you provide this information, I'll be able to give you more targeted advice on how to resolve the issue.
