The documentation on Custom Actions says in step 5:
Navigate to to the Schemas (bot/runtime/azurewebapp/Schemas) folder and then run the command update.sh.
You will see that the partial schema (MultiplyDialog.schema inside customaction/Schemas) has been appended to the default sdk.schema file to generate one single consolidated sdk.schema file.
Copy the newly generated sdk.schema into the schemas (bot/schemas) folder at the root of the ejected runtime.
In version v1.0.1 of the Bot Framework Composer, after ejecting the runtime, the Schemas folder is missing in both:
It appears the schema files & corresponding scripts have moved to:

Steps to reproduce the behavior:
The documentation should be updated to reflect the functioning of the new scripts path, and the sdk.schema does not need to be copied anymore:
Navigate to to the schemas (bot/schemas) folder. This folder contains a Powershell script and a bash script. Run either of these scripts ./update-schema.ps1 -runtime azurewebapp or sh ./update-schema.sh -runtime azurewebapp. To use the Azure Functions runtime, run the script with -runtime azurefunctions. The runtime azurewebapp is chosen by default if no argument is passed.
Validate that the partial schema (MultiplyDialog.schema inside customaction/Schema) has been appended to the default sdk.schema file to generate one single consolidated sdk.schema file.
The above steps should have generated a new sdk.schema file inside schemas folder for Composer to use. Reload the bot and you should be able to include your new custom action!

@bartbilliet I just reproduced this issue. Thanks for reporting.
@luhan2017 Please let me know if there anything I should update in the doc.
@bartbilliet it was moved to the botfolder/schemas folder. For now, you can just run updateSchema command under the schemas folder, you don't need to do an extra copy from runtime/schemas to schemas folder right now.
@zxyanliu please help update the doc based on the above.
Hi @bartbilliet, here is a working PR to address this issue. Please also be noted that you might need to restart your electron to see the custom action enabled in Composer UI when testing it. I also added a Note box in the PR for this known issue. The content will go live soon.
Thanks!
@zxyanliu I believe the composer-docs-pr repo might be private, as I'm unable to follow the PR link. Anyway, I'll see when the content goes live then. Thanks for the updates! :-)
Hey @bartbilliet thanks again for reporting this issue. The content has been updated and will go live soon.
