Error with Temperature for SEBAL

Question

I want to create a layer of surface temperature for SEBAL model. I am using the standard model for LST for Landsat 8. When I run the code the following error occurs: Temperature: Layer error: ImageCollection.mosaic: Error in map(ID=LC08_159042_20210106): Number.log, argument 'input': Invalid type. Expected type: Number. Actual type: Image<[Enb]>.

function addLST(image) {
  var Rc = image.select('ST_B10').multiply(0.00341802).add(149.0);
  var K1 = ee.Image.constant(774.8853);
  var K2 = ee.Image.constant(1321.0789);
  var t0 = ee.Number(image.select('Enb').multiply(K1).divide(Rc).add(1)).log();
  var t1 = K1.divide(t0).rename('Temperature');
  return image.addBands(t1);
  
} 
var filtered=filtered.map(addLST);  
Map.addLayer(filtered.select('Temperature'), {palette : ['blue','pink','brown','orange','yellow','green']}, 'Temperature');

Answer 1

I used the 'system:index' of image in error message and, I found out the exact product id that you are using: LANDSAT/LC08/C02/T1/LC08_159042_20210106. If you didn't rename band for obtaining LST, this is 'B10'; not 'ST_B10'. On the other hand, RADIANCE_ADD_BAND_10 is 0.1; not 149 as it is in your code snippet.

Taking above considerations, I modified your code as follows by using a more intuitive approach with expressions.

var dataset = ee.ImageCollection('LANDSAT/LC08/C02/T1')
  .filterMetadata('system:index', 'equals', 'LC08_159042_20210106');

var image = dataset.first();

print(image);

print('RADIANCE_MULT_BAND_10',image.get('RADIANCE_MULT_BAND_10'));
print('RADIANCE_ADD_BAND_10',image.get('RADIANCE_ADD_BAND_10'));
print('K1_CONSTANT_BAND_10',image.get('K1_CONSTANT_BAND_10'));
print('K2_CONSTANT_BAND_10',image.get('K2_CONSTANT_BAND_10'));

Map.centerObject(image);
Map.addLayer(image);

function addLST(image) {
  var Rc = image.expression(
    'L*0.0003342 + 0.1', 
    {'L': image.select('B10')});

  var t1 = image.expression(
    '(1321.0789 / log (774.8853 / Rc + 1)) - 273.15',
    {'Rc': Rc}).rename('Temperature');

  return image.addBands(t1);
  
}

var parVis = {"opacity":1,
                 "bands":["Temperature"],
                 "min":12.563630937215294,
                 "max":29.057135926564285,
                 "palette":['blue','pink','brown','orange','yellow','green']};

var filtered = dataset.map(addLST); 

print(filtered);

Map.addLayer(filtered.select('Temperature'), parVis, 'Temperature');

After running above code in GEE code editor, I got result of following picture without any problem:
