Error when adding pictures to report

Hi,

In my database I have a field that holds images. The images there are generated png files.
When I try to add it to my report, I add the format for the value as ${bitmap:150x50}.

It worked for some time but now I always get the error:

ERROR org.docx4j.openpackaging.parts.Parts    - Couldn't delete part /xl/drawings/_rels/drawing1.xml.rels - nothing by that name

followed by

INFO  c.h.r.libintegration.CubaReporting      - Finished report [Warenkorb Artikel] with parameters [
entity:de.kneitzel.laserparadise.entity.Warenkorb-512 [detached]]
WARN  c.h.c.web.sys.CubaApplicationServlet    - Too long request processing [11846 ms]: ip=192.168.0.184, url=/lp/UIDL/

Any idea what is going wrong on my server? I am running the server on debian linux.

Would be great if you could asssist with this issue. Tell me, if you need more information. Thank you.

Ok, seems that I was distracted by the first error message. This error is at least not causing, that the report is not generated.

My core problem was just the timeout. Generating a report with multiple pictures seems to take a lot of time. So after increasing the timeout from 10 to 30 seconds, my reports was running fine again.

Regarding the first message: I will have a closer look to see if this could be the result of a missing picture or something like that.
