Anypoint Studio ERROR despite everything working correctly

I have created endpoint in Mule Soft which contains data from 3 separate APIs (2 REST and 1 SOAP), but despite working correctly it return an error:

ERROR 2021-12-22 00:24:23,483 [[MuleRuntime].uber.04: [projekt_isi].Found_course_response.BLOCKING @3d5f454f] [processor: Found_course_response/processors/6; event: 1dd95df0-62b5-11ec-902a-d481d75d7926] org.mule.soap.internal.generator.attachment.AttachmentResponseEnricher: Could not close XMLEventWriter

Because this request takes pretty long time I am guessing that this ERROR causes it, but all I found on internet was that it is problem with XML conversion that is supposedly already resolved. Have you ever encountered such problem? It is strange to especially since I get correct JSON response which contains both JSON responses from REST APIs as well as converted XML response from SOAP API.

Here is how the Flow looks like:

EDIT: As requested here is whole Error:

Please provide details to understand the issue and be able to help you. The screenshot provides very little insight onto what the flow does. Instead paste the flow as XML text. Add versions of Studio, Mule and any connector in the flow. The error message may contain more details of the error and its location in the flow. If there are details please add them too. Even so, defining the Java property mule.verbose.exceptions=true could add a stack trace of the error. – aled
"I found on internet was that it is problem with XML conversion that is supposedly already resolved." additionally if you found some information on the issue you should share the source link and details so others can avoid redoing that part of the investigation. Note that the solution for other software may not be relevant for your Mule version. – aled
I have added missing information as you requested. I did find out that error message I found was actually not about my case in the end. – Curiosity

Try upgrading the Web Service Consumer from current version 1.6.6 to latest version 1.6.7. It should resolve the printing of that error message.
