Error when exporting dataset, independent from file format

[Mar-Cald]

Dear all,

I am trying to download my dataset from ASReview Lab but this error occurs:

TypeError: send_file() got an unexpected keyword argument 'download_name'

I am not able to download anything, neither data (in any format) nor the project.

Two months ago, I started the project and I was able to download the dataset without any errors occurring, now I am trying again but it doesn't work.

Could someone help me with that, please?

Here is the entire output if I try to download the dataset in .csv format:

During handling of the above exception, another exception occurred:

You might have installed another Python package in the meanwhile that downgraded one of our dependencies. The solution is simple and described here: #1166 (comment)

Hi,
thank you!
I have tried to upgrade flask but the problem persist. Do you have any other suggestion?

[Mar-Cald]

May I have to upgrade also ASReivew lab?

[J535D165]

Not likely. Can you show me the output of pip show asreview and pip show flask?

Hi,
I have finally solved the issue typing:

pip install flask==2.1.0

Thank you for your help!
