Problems consuming a service

0
Hello everyone, I'm using a REST service in Mendix to retrieve a list of products. The service works correctly and returns products, but only those that don't have "oferta". When I try to search for a product that does have "oferta", it doesn't appear in the results. For example, here we see that when searching for insulin, the "oferta" field is empty; therefore, it searches for the product without any problem. when searching for this, the respective query is made. But when I search for a product that does have data in "offer" it doesn't let me and I get an error. For example, here I search for amoxicillin, it does have data in [oferta] and when I try to search for it in the app I get an error.  This is the domain model that is generated when mapping the JSON format. I have created the input entity to search by product name. This is the structure of the import mapping And this is my microflow where I call the service, please tell me what I need and how do I solve this, thank you very much

Of course, it seems the error occurs in the microflow where the service is called. I tried putting some breakpoints and when I searched for an object with "oferta" it doesn't even pass the call to the service. I don't know what could be happening.

Yes, this appears to coincide with an invalid character error, as can be seen below. image.pngApparently it is a problem with the accents. Each word with an accent, in this case cafeína, is replaced with an invalid character = cafe¡na 

 

How do I solve this?

Hi Eric, 

 

You can set the headers in the GET request to get response from API only in a particular charset in this case UTF-8 (if the server honors the value). 

https://http.dev/accept-encoding

 

Or you can store the response in a string, do string manipulation to remove/replace this data and then import. 

 

Try your luck!

Raghav
