Frequently Asked Questions

Q: I am using a free tier subscription and my Workbench deployments fail due to insufficient VM cores quota, is there anything I can do to work around this?

A: Delete your failed deployment. Change the VM SKU in step 8 of the "Deploy Blockchain Workbench" section of the deployment guide to a "Standard DS1 v2" and ensure you do not have any other virtual machines deployed on your subscription before deploying Workbench again.

Q: How to I upgrade my old AAD application to be compatible with Workbench 1.5.0 and later

The AAD application manifest has slightly changed for Workbench 1.5.0 and later, we've provided upgrade instructions and script to help you upgrade your old AAD application.

Q: I'm trying to access Workbench's API programmatically (using a service principal) but I get errors when calling the API.

If you are getting 204 (NO CONTENT), 401 (UNAUTHORIZED), 403 (FORBIDDEN), or 404 (NOT FOUND) when you access Workbench's API using a service principal it may be due to service principal not having admin privileges or not being assigned to the correct application role to take that action. Please take a look at Workbench service principal for creating and giving a service principal admin privileges. There is also this great article that discusses programatic access of Workbench and application role assignment.

Q: Workbench performance is very slow for me. How can I scale up/out to improve performance?

A: When there are many users interacting with Workbench, pages load/refresh slowly. Refer to our scale up/out guidance.

Q: I'm getting error messages when taking actions such as creating a contract or taking action on a contract. How can I troubleshoot the problem?

A: We leverage Application Insights to give you detailed troubleshooting information. Refer to our troubleshooting guide for instructions and more information.

Q: I'm having trouble setting up AAD integration with Workbench. What steps do I need to take to do this post deployment?

A: You can refer to our AAD setup instructions for instructions and more information.
