demos/alert-to-slack-with-logic-app -> InvalidTemplate

[SergiuSofroni]

Hi there.

Wanted to use 'demos/alert-to-slack-with-logic-app' but there are some issues.

While trying to follow the Steps from Readme on 'Click on Outputs. Copy the output called WebHookURI.' I got the below
Use 'listCallbackURL(resourceId('Microsoft.Logic/workflows/triggers', parameter('logicAppName'), 'manual'), '2019-05-01').value' to retrieve the callback URL, the value contains a secret and is not recommended in an output.

Solved this, but when I try to run that logic app, got the below error and don't know how to solve it
InvalidTemplate Unable to process template language expressions in action 'Http' inputs at line '0' and column '0': 'The template language expression 'triggerBody()['context']['portalLink']' cannot be evaluated because property 'context' doesn't exist, available properties are 'schemaId, data'. Please see https://aka.ms/logicexpressions for usage details.'.

Can anyone help on that?

Thx.
