Mapquery errors ( Error in validObject(object = value))

[mainyanghr]

Dear Sir or Madam,

I have been struggling to debug mapquery for several days for CITE-seq. I used PBMC-multimodal-2023 as my reference. Error in validObject(object = value) :
invalid class “Assay” object: Keys must match the pattern '^[a-zA-Z][a-zA-Z0-9]*_$' Could someone help? Thank you all very much!
