"Error while loading from location 'repository_folder/process_name': empty string"

Hello,
I want to to start a certain process. But I get the error shown in the question. It is a process of an elder RM-version (5.3). Other processes of this version still work.
What can I do?
Thanks in advance,
Ralf :-)

It sounds like the process refers to a location that doesn't actually exist. Did you check your repository path hasn't changed since the prior version?

Hi Brian,
thanks for your answer.
The location really exist. The respository path is absolutely the same.
In the details you can read the bug description:

Hi @ralf_kretschmer,

can you possibly share the process? If not publicly, you can also PM it to me so i can have a look. It seems there is something going wrong during the process import. Guessing from the stacktrace, there is some wrong information on the operator or annotation position (x, y or width).

Cheers

Jan
