Custom Connector- 404 Resource Not Found

Hello there,

 

I am building an app with a Pen Input for signatures.  I will eventually save the data from Powerapps to OD4B as a .htm file then, convert it to a PDF.  

 

I am trying to pass the Pen Input image to Flow using a Custom Connector an a Swagger file as described in this video by @Anonymous:

https://www.youtube.com/watch?v=mp-8B1fLrqs&feature=youtu.be

I have double checked my host and base path. 

 

I also updated my host path omitting the :443 as he indicated in this article:

http://www.cleverworkarounds.com/2017/11/13/a-sample-openapiswagger-file-for-powerapps/comment-page-1/

 

Here is my swagger file for reference:

{
 "swagger": "2.0",
 "info": {
 "description": "Convert the signature of a waiver",
 "version": "1.0.0",
 "title": "WaiverHandler"
 },

 }
 },

}

No matter what I do I cannot get the PenInput.Image to Flow.  I have tried to recreate the flow, recreate the swagger file and have recreated the custom connector a dozen times.  No dice.  Can anyone help me with this?

    Didn't tried this.

    But there is a much easier way to pass the image for Pen Input control from PowerApps to Microsoft Flow:

    The No-Code solution to Save Picture Files from PowerApps to Flow

     

    Please take a look at the method mentioned in the blog above to check if it works for your scenario.

     

    If you would like to keep working on the custom connector part, please post back to let me know.

    Regards,

    Michael
