[hsu0414]

Dear All,

When I try to download the Meteorological Data using the tool in QGIS3.
It showed task failed and the log was below:
It said AttributeError: 'NoneType' object has no attribute 'flush'
Do you have any idea about this issue? Thank you very much.

I cannot replicate your error but I notice that the plugin is unstable. I also get errors some time but not the same as yours. Can you check the following:

1. Make sure that you have the CDI API configured correctly. Look at this link: https://cds.climate.copernicus.eu/api-how-to
2. Make sure that you point to a folder where you have read and write access, e.g. the Documents-folder
3. Open your Python console in QGIS and try again. Now you will see more detailed log messages that might tell us what went wrong.

Thank you. I can complete the task now.
The only difference between now and before is I reinstalled the QGIS 3.20.2 through the Advanced Install of OSGeo4W Network Installer and I fully installed all packages (blindly).
So, I guess it was because I lack some packages to run it, although I still don't have the idea of what it is.

Here are some info on the module packaging:
