That is the first time I’ve seen that error.
Does that happen with any element and application or a specific one ?
Does it happen when saving the workflow or while recording, or when running the workflow ?
What if you close the designer/workflow and run it? Select it under the open workflow tab and press the run button, but it’s important that the designer is NOT open.
When I run it from here. There is no error message but no value is returned in the GetElement.
I have tried to copy your video on youtube for using the calculator to ensure that it is a good test.
That is truly odd.
I cannot remember if or why there should be any json serialization doing running, unless maybe for the cache …
try going to Settings tab click recorder plugins, select windows and disable cache
OpenRPA is going to be slow, but if it fixes the problem for now, i guess it’s a work around
