Data cannot be processed with new custom connector

[shalowsoup]

Hello, I'm trying creating a custom connector.

When I make "GET" connector with proper URL, ( which was working collectively in Postman)

However, when I use on Power Automate, it becomes an error with a following message.

InvalidTemplate. Unable to process template language expressions in action 'test' inputs at line '1' and column '2757': 'The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['xxxxxxxxxxxxxxx']['connectionId']' cannot be evaluated because property 'xxxxxxxxxxxxxxx' doesn't exist, available properties are 'xxxxxxxxyyyyyyy'. Please see https://aka.ms/logicexpressions for usage details.'.

What should I look up to solve this error?

Hi @shalowsoup 

Is this flow being triggered from a Power Apps control? If so, this is a very common error and can be resolved by removing the flow from the power apps control and then add it again over there. 

If not, can you share more details on the trigger type so that we can better understand the issue and help you with this? 

Hope this Helps!
