Displaying of bands for multiple datasets in Google Earth Engine

I am classifying landsat 8 and sentinel 1 in google earth engine but the console tells me i do not have the required bands for classification even after assigning all the bands.
Please find attached a link to my work flow
……… javascript for GEE

                  .filterBounds(mis)
                  .map(maskL8sr)
                  .median().clip(mis);
