Error: The given key was not present in the dictionary with several Excel acitivites

Hello together,

when running the program a datatable is filtered and the result is written into Excel with a write range activity or in another case with a write cell activity after using assign to get the value.

This procedure is applied for several different Excel files. Sometimes it works and sometimes I get the error: “The given key was not present in the dictionary with several Excel activities”.

I tried it with a log message and there is no error occurring. I don’t use any dictionary in the process. So I really don’t know how to solve the problem. I even updated the packages already.

I found that post but the solution is not documented so well therefore I can’t solve my issue.

Thank you in advance!

I noticed that this error only occurs with “own” write range and write cell activities. When using excel application scope the error is not occurring.

It did work previously with both activities. Is it a bug?
