Hi @heavy-metal-guy thanks for raising this issue.
I took a look on why this is happening and most of the cases the reason on why this happens is due to the customer firewall. When the user opens the desinger whe make sure that the extension bundle also gets downloaded. In this case due to the firewall it doesn't gets downloaded.

• Could you please check if you have the extension bundle in the following directory? <username> its just a placeholder. That should be your username.
  /Users/<username>/.azure-functions-core-tools/Functions/ExtensionBundles/Microsoft.Azure.Functions.ExtensionBundle.Workflows/

• If indeed you are using a custom firewall, could you try amending firewall to allow downloading it?

Hi @ccastrotrejo ,
Thank you for your response.
I have Microsoft.Azure.Funtions.ExtensionBundle.Workflows downloaded. Version 1.87.34.
I disabled firewall and tried to open designer. Still get an error:

Hi @heavy-metal-guy, this seems to be a backend issue related to the extension bundle, that th reason on why I transferred it to this repo. I will contact the backend engineers to se see what we can do about it. I will update the thread as soon as I know there is a fix or a workaround.

@ccastrotrejo ,
Do you have any feedback from backend engineers?

[ccastrotrejo]

Hi @heavy-metal-guy not yet.
Also could you please check which version of the logic apps extension bundle you have?
/Users/<your-username>/.azure-functions-core-tools/Functions/ExtensionBundles/Microsoft.Azure.Functions.ExtensionBundle.Workflows should be the folder with the latest version in this path in your computer

Tagging some BE engineers on this.
@AbodeSaafan, @swghimire is there any chance you can help us to take a look at this?

[AbodeSaafan]

@heavy-metal-guy Do you have storage emulator or azurite running and the connection string set to use dev storage. The connection string is set to that automatically when you create a workflow in VSCode but please check that your local storage emulator is running, that might be the problem here

[heavy-metal-guy]

Hello
@ccastrotrejo
Thank you for the response. I have installed Logic Apps (Standard) v4.107.4 and Azure Functions v1.16.1. Path that you mentioned contains folders: 1.87.34, 1.91.14 and 1.94.13. That's why I tried to install different versions of extensions. Thoug those folders are no related to extensions versions in VSCode.

@AbodeSaafan
Thank you for your answer. I use azurite. Though I think there might the problem with the configuration. Thanks for the suggestions. I'll try to install it again manually.
