Unable to use environment variable in custom connector

Posted on by MM-02040739-0

Steps to use environment variables in custom connector is provided in docs here: Use environment variables in solution custom connectors | Microsoft Learn

However, I am getting following error even though following every step in the article

The request failed with client error: 'Invalid Api definition object. Please specify a valid Swagger 2.0 Url and valid list of ServiceUrls.'. The correlation Id is '3abc1c0f-633a-4361-8fb6-37b7bdece90b'.

This is my swagger of the custom connector

swagger: '2.0'
info:
title: ProQuote - Data Integration
description: ''
version: '1.0'
host: '@environmentVariables(''pcw_DATAIntegrationCustomConnectorHost'')'
basePath: /ttpm
schemes:
- http

I can attest to the fact that the environment variable exists

can you try this and see if it works

swagger: '2.0'
info:
title: ProQuote - Data Integration
version: '1.0'

basePath: /ttpm

schemes:
- https

paths:
/quotes:
get:
operationId: GetQuotes

description: Success

Then set host via environment variable in connector UI (not in Swagger).

I believe that you cannot use environment variables in Swagger host

Fix by:

Use static placeholder host in Swagger

Swagger is only for definition. Can you share with us the link to the documentation?

Document states we can use an environment variable, which is correct, but what we say here dont use the environment variable in the swagger definition.

environment variable can be used on other places like client id , sec etc

Swagger UI does not support path templating, and should be a valid host. Please find the link below for reference
