Describe the bug
I am using the robvis web app with a ROB2 dataset.
My file is recognised correctly in the "Review your data" section: all expected columns are displayed correctly, including the Overall risk of bias column and the Weight column. However, when I try to generate the traffic-light plot, the app still fails and shows an error.
The error message shown is:
"An error has occurred. Please double-check your that your selected tool matches the data you uploaded (common problem)."
In my case, the selected tool does match the uploaded data, so this seems to be a plotting-stage bug rather than a data-recognition problem.
To Reproduce
- Open the robvis web app
- Select RoB 2.0 as the assessment tool
- Upload a ROB2 dataset
- Confirm that the data preview correctly shows:
- Study
- 5 ROB2 domains
- Overall risk of bias
- Weight
- Click Generate Plots
- Go to the Traffic-light plot page
- The app shows the error instead of generating the plot
Expected behavior
The web app should generate the traffic-light plot normally, because the uploaded file is correctly recognised as a ROB2 dataset and the required columns are present.
What I already tried
I have already tried the following, but the issue still persists:
- confirmed that the selected tool is RoB 2.0
- confirmed that the dataset contains both Overall risk of bias and Weight
- cleaned and standardised the file
- tried both CSV and XLSX
- tried renaming study labels to simpler ASCII-only text
- retried after re-uploading the file
The data preview is still correct, but the traffic-light plot fails.
Screenshots
I can provide screenshots showing:
- the correctly recognised data preview
- the traffic-light plot error page
Desktop (please complete the following information):
- OS: Windows
- Browser: Edge
- Version: latest available on my system
Additional context
I noticed that in issue #170, a similar problem was discussed.
In my case, however, even after checking the tool type and data structure carefully, the problem still occurs.
So this may be a web app bug affecting some valid ROB2 files during the plot generation step.
