HTTP request error because of "ç" character (byte code E7)

Posted on by bpeixoto

Hi.

I'm posting data to an URL using HTTP connector in Power Automate.

The data is being posted to a REST API and the answer contais the character "ç".

Because of this, the HTTP connector returns the error "Http request failed as the content was not valid: 'Unable to translate bytes [E7] at index 55 from specified code page to Unicode.'."

Due to this problem the flow breaks and i cannot send a proper answer.

I cannot change the REST answer since is a third party API.

Is there anyway to bypass this problem?

in your HTTP action you can specify what the type and code page of the return message is supposed to be. Usually you want UTF-8 or better, but you might be able to also specify your local code page.

Hi Ibendlin and thank you for the answer.

You mean, inform in power automate, in the header something like "Content-Type: text/html; charset=UTF-8"?

I already tried that, without success.

I ended up creating a new step to treat that as an error.

Thank you for answering Ibendlin.

Could you share how you treat it as an error? I have the same issue with the next error details.

I can't change the API response content, so I need to fix it somehow. The API response content look like this:

Thank you 😊

Hi.

In my case i have created a step just after the HTTP request with the configuration "Run After" marked as "has failed".

For me that worked because the special character that is causing me problems is shown only when the login process fails so i'm not trying to parse it anymore.

Maybe in your case it won't work.
