Custom connector error "JSON parsing error, expected 'object' but got 'string'.",

[WebPortal]

I've got a custom connector that calls an Azure Function as Web API.

The API is working well, and returning a JSON as response.

It seems Power Apps does not like strings as responses, so after a very extensive research, I've updated the function to dump the content as JSON.

All I want is to call the web API and get the response in a label.

So, I have a button with:

Set(resposta, TesteAPI.httpexample(TextInput1.Text))

And a label with:

resposta.body

But resposta is empty.

And from the monitor, I see that the API is correctly executed:

But the response isn't updated:

This is my API defintion:

swagger: '2.0'
info: {title: TesteAPI, description: '', version: '1.0'}
host: xxx.azurewebsites.net
basePath: /api
schemes: [https]
consumes: [application/json]
produces: [application/json]
paths:
/httpexample:
get:
responses:
default:
description: default

properties:

responseType: {type: string, description: responseType}
x-ms-visibility: important
summary: devolve o nome
description: apenas um exemplo ok
operationId: httpexample
parameters:
- {in: query, name: name, type: string, required: true}
definitions: {}
parameters: {}
responses: {}
securityDefinitions: {}
security: []
tags: []

I've tried a million things but nothing works, I've read the whole Azure, Power Apps and Swagger documentation but nothing works. This should be so easy.

Can anyone help?

Thanks in advance!

Hi @WebPortal,

I had a similar issue - still not sure why is it happening.

The way I did it, create a flow which executes you API call on PowerApps button click, and use the flow to return the value for use.

please let me know if you need further assistance.
