Error handler returns nothing for 400 errors

[rgasch]

We have fundamentally working integration. However, sometimes we get a 400 Error and in this case, the following code

$errorHandler = $this->_connector->getLastError();
CliLog::error("API: Http Status Code = " . $errorHandler->getHttpStatusCode());
CliLog::error("API: Error Message = " . $errorHandler->getIntuitErrorMessage());
CliLog::error("API: Error Element = " . $errorHandler->getIntuitErrorElement());
CliLog::error("API: Error Detail = " . $errorHandler->getIntuitErrorDetail());
CliLog::error("API: Error Code = " . $errorHandler->getIntuitErrorCode());
CliLog::error("API: Error Type = " . $errorHandler->getIntuitErrorType());

All these calls other than the getHttpStatusCode() call return nothing.

Is this a bug or are we using an incorrect method to get the cause of a 400 error?

Experiencing this same issue

[sashidharg]

Have the same problem.

This might be because the code expects the quickbooks response header as "application/xml" while the actual response has "application/xml;charset=UTF-8".

The code at IntuitResponse::setFaultHandler() expects "application/xml".

if($this->getResponseContentType() != null && (strcasecmp($this->getResponseContentType(), CoreConstants::CONTENTTYPE_APPLICATIONXML) == 0 || strcasecmp($this->getResponseContentType(), CoreConstants::CONTENTTYPE_TEXTXML) == 0)){ $this->faultHandler->parseResponse($body); }

OK, I tried to figure out how to fix this, but didn' t get all that far, since for some reason the parsing fails, there's nothing more to work with using the available SDK code. However, I have a workaround:

When you call your API Client function - in this example it's Add() - do this:

return $this->_getConnector()->throwExceptionOnError(true)->Add($entity);

Then in the code that calls this function, switch to try/catch:

try {
    $response = $this->add($object);
} catch (\Exception $e) {
    $this->_printApiError($e);
    return null;
}

Finally, here's the method that parses the exception text using the Laravel Str helper class in a very quick and dirty manner, I spent like 5 minutes writing this:

    private function _printApiError(\Exception $e): int
    {
        $xmlString = Str::between($e->getMessage(), '">', '</IntuitResponse>');
        $xml       = new \SimpleXMLElement($xmlString);

        // Extract error details
        $errorCode    = (int) $xml->Error['code'];
        $errorMessage = (string) $xml->Error->Message;
        $errorDetail  = (string) $xml->Error->Detail;

        // Log the extracted error details
        CliLog::error("API: Http Status Code = " . $errorCode);
        CliLog::error("API: Error Code = " . $errorCode);
        CliLog::error("API: Error Message = " . $errorMessage);
        CliLog::error("API: Error Detail = " . $errorDetail);

        return $errorCode;
    }

Like I said, this is quick and dirty and could certainly be improved, but at least now you're able to see what error you got and work with this info.

This worked for me.

$error = $this->data_service->getLastError();

if ($error) {
   $err = $error->getResponseBody();
}

getIntuitErrorMessage() was returning an empty string. With the solution above, I was able to get the error from the response body
