API Access Issue for Public Dataset "bladder_msk_2025" from Published Study

[阿力米热]

Dear cBioPortal Support Team,

I'm encountering technical difficulties when attempting to access the public dataset referenced in the publication:  

"Clinical Outcomes, Genomic Heterogeneity, and Therapeutic Considerations Across Histologic Subtypes of Urothelial Carcinoma"

(Data sharing statement: "Data are freely available at https://www.cbioportal.org/study/summary?id=bladder_msk_2025")

While the study summary page loads correctly via the web interface, API requests return HTTP 400 errors with the following details:

Error Observations:

1. Endpoint:`POST /api/treatments/display-patient`  

   - Response: `{"message":"studyIds size must be between 1 and 10000000"}`  

   - Request payload: `"data": "[]"` (appears empty)

2. Endpoint:`POST /api/clinical-event-type-counts/fetch`  

   - Response: `{"message":"interceptedStudyViewFilter size must be between 1 and 2147483647"}`  

   - Request payload: `{"studyIds":[]}` (empty array)

Troubleshooting Attempted:

✓ Successfully accessed study overview via direct URL  

✓ Verified no institutional access restrictions apply  

✓ Observed consistent errors across multiple browsers

Specific Queries:

1. Does the `bladder_msk_2025` study require special parameters for API access?  

2. Could this be related to recent API specification changes?  

3. What is the correct request format for these endpoints with this dataset?

I would greatly appreciate guidance on:

- Required parameters for these API calls  

- Any known issues with this specific study  

- Recommended workarounds to access the treatment and clinical event data

Please let me know if you require:

- Full HAR logs of the requests  

- Screenshots of the web-to-API workflow  

- Additional diagnostic information

Thank you for maintaining this invaluable resource for cancer genomics research.

Best regards,  

Alimire

Hello Alimire,

The study is currently not in the portal. We are working with the authors to finalize the study for the portal. We will be making the cohort public shortly. 

Apologies for the inconvenience. 

Thanks,

Ritika
