Gpt sentinel-1 back-geocoding error

Microwave Toolbox
22

@ABraun thanks a lot for your help. I followed the installation choosing “Yes, try deleting SNAP user data” and I have now SNAP v 8.0. However, the same code that was working well now returns these two errors above using the function:

def terrain_correction(product,prj) :
    parameters = HashMap()
    parameters.put('sourceBandNames', 'Amplitude_VV')
    parameters.put('demResamplingMethod', 'CUBIC_CONVOLUTION') 
    parameters.put('imgResamplingMethod', 'CUBIC_CONVOLUTION') 
    parameters.put('demName', 'SRTM 3Sec') 
    parameters.put('pixelSpacingInMeter', 10.0)
    parameters.put('externalDEMApplyEGM', True)
    parameters.put('saveSelectedSourceBand', True)
    parameters.put('mapProjection', prj)
    parameters.put('nodataValueAtSea',False)
    parameters.put('maskOutAreaWithoutElevation',False)
    return GPF.createProduct("Terrain-Correction",parameters,product)

Do you have any hint for it? Thanks a lot
