Errors in checking mutations on certain genes

[PUTRA, Hadi (CAMBRIDGE UNIVERSITY HOSPITALS NHS FOUNDATION TRUST)]

Dear cBioPortal Team,

I have encountered errors since yesterday when I want to check the recurrence of certain genes (POT1 and TET2) in the cBioPortal database. Here is the error I received:

{"type":"ErrorBoundary","log":"TypeError: Cannot read properties of undefined (reading 'length')","url":"https://www.cbioportal.org/results/mutations?cancer_study_list=all_stjude_2015%2Call_stjude_2016%2Cbll_target_gdc%2Clcll_broad_2013%2Ccll_broad_2015%2Ccll_broad_2022%2Ccll_iuopa_2015%2Ccllsll_msk_2026%2Ccllsll_icgc_2011%2Cchl_sccc_2023%2Cctcl_columbia_2015%2Cdlbcl_dfci_2018%2Cdlbc_broad_2012%2Cdlbcl_duke_2017%2Cmbn_msk_2024%2Cdlbc_tcga_pan_can_atlas_2018%2Cdlbclnos_tcga_gdc%2Cnhl_bcgsc_2013%2Cdlbc_tcga%2Clymphoma_cellline_msk_2020%2Cmcl_idibips_2013%2Cmbn_sfu_2023%2Cmbn_mdacc_2013%2Cmtnn_msk_2022%2Cmm_broad%2Cnhl_bcgsc_2011%2Call_phase2_target_2018_pub%2Cpcnsl_msk_2024%2Cpcnsl_mayo_2015%2Calal_target_gdc%2Caml_ohsu_2022%2Caml_ohsu_2018%2Caml_target_gdc%2Caml_tcga_gdc%2Claml_tcga%2Claml_tcga_pub%2Claml_tcga_pan_can_atlas_2018%2Cmnm_washu_2016%2Chdcn_msk_2025%2Chistiocytosis_cobi_msk_2019%2Call_stjude_2013%2Cmds_tokyo_2011%2Cmds_mskcc_2020%2Cmds_iwg_2022%2Cmpn_cimr_2013%2Caml_stjude_2024%2Caml_target_2018_pub&Z_SCORE_THRESHOLD=2.0&RPPA_SCORE_THRESHOLD=2.0&profileFilter=mutations%2Cstructural_variants%2Ccna%2Cgistic&case_set_id=all&gene_list=TET2&geneset_list=%20&tab_index=tab_visualize&Action=Submit"}

Hi, 

We encountered a similar issue on our local instances. Exept that the reading was chromosome not length. 

Apperently it now works again without any changes from our side. Did you already fixed this problem ?

Does our Instance use the frontend Version of the public cbioportal, because we did not update anything bevore and after the issue was found. 
I will let you now if the issue comes up again. 

Thanks for your work. 

Elias.

Hi,

This issue has been resolved - thank you for your patience. It was related to a recent change in Genome Nexus. Please let us know if you still have issues.
