Custom Connector - Dynamic Parameters

(0) ShareShare

Posted on by 1

Hi there,

 

We've ran into the issue building a custom connector (full details here https://github.com/weng5e/flow-connector-trigger/issues/1). 

 

We want to build a custom connector that will be registered in App Source and will need to dynamically generate parameters to avoid having to Parse JSON after each time the connector/action is used. We have found a sample here (https://github.com/weng5e/flow-connector-trigger) that should work for us but results in the error.


Really blocked on this, so would appreciate anybody that can help.

Original message from my colleague on GitHub:


Hi,
I've encountered a problem with Webhook Trigger With Dynamic Parameters.
When I'm trying to save Flow it prompts me with an error message
The response from API 'test-2ddynamic-5f1682ac231a8d2257-5f26430bdda5351998' operation 'GetWebhookResponseSchema' with status code '200' does not contain a valid OpenAPI schema object.

I'm using copy-pasted connector definition from this repo (https://github.com/weng5e/flow-connector-trigger/blob/master/connector-definition/5eDynamicParameter.swagger.json).
My API (also straight from this repo) is hosted under https://radiant-everglades-34403.herokuapp.com/index.html
