An error occurred during the
log of the request content. Explanation message: '%1'.
Something went wrong while logging an HTTP payload with a content-type that might not be
supported by the underlying log system (cisterna). Such an attachment will simply not be
logged with the other events and won't be available in the Test Log explorer.
In case the content type is a commonly used one, consider creating a feature request to get
this content-type supported by the product.
