why cesium can not display the terrain?

[Brilliant-orange]

There was a problem loading the terrain in cesium. The cesium globe displays normally after removing the terrain.
In cesium1.96, chrome displays the following error:
Cesium.js:85 An error occurred in "Py": Failed to obtain terrain tile X: 0 Y: 0 Level: 0. Error message: "RangeError: Invalid typed array length: 8894653434"
Cesium.js:85 An error occurred in "Py": Failed to obtain terrain tile X: 1 Y: 0 Level: 0. Error message: "RangeError: Invalid typed array length: 2017542741"

cesium code like this:
var terrainProvider1=new Cesium.CesiumTerrainProvider({
url:"http://localhost:9000/"
});
const viewer = new Cesium.Viewer("cesiumContainer", {
baseLayerPicker: false,
imageryProvider: imageryProvider,
terrainProvider:terrainProvider1
});
viewer.scene.globe.enableLighting=true;

However, in the latest cesium, chrome does not output any errors and just does not display the globe.
How can I solve this problem? @homme @thomas001 @chris-cooper @tmizu23 @kyosho-

@Brilliant-orange I faced the same problem. Unzipping generated tiles solved the issue for me.

Would you mind tell us how did you do that?
I have this problem and i don't know how to unzip terrain files.
thanks.

写.terrain时，不能用gzwrite，那样写不出正确的.terrain，而是用fwrite方式.
修正如下：在terraintile.cpp中改写

void Terrain::writeFile(const char fileName) const
{
FILE terrainFile = fopen(fileName, "wb");

if (terrainFile == NULL) {
    throw CTBException("Failed to open file");
}

// Write the height data,float应该是4 * TILE_CELL_SIZE
//if (gzwrite(terrainFile, mHeights.data(), TILE_CELL_SIZE * 2) == 0)
if (fwrite( mHeights.data(),  sizeof(i_terrain_height),TILE_CELL_SIZE, terrainFile) == 0)
{
    fclose(terrainFile);
    throw CTBException("Failed to write height data");
}

// Write the child flags
if (fputc(mChildren,terrainFile ) == -1) {
    fclose(terrainFile);
    throw CTBException("Failed to write child flags");
}

// Write the water mask
if (fwrite(mMask,sizeof(char), mMaskLength,terrainFile ) == 0) {
    fclose(terrainFile);
    throw CTBException("Failed to write water mask");
}

fclose(terrainFile);

}
/*
void Terrain::writeFile(const char *fileName) const

    gzclose(terrainFile);

// Write the water mask

    gzclose(terrainFile);
    throw CTBException("Failed to write water mask");
}

// Try and close the file
switch (gzclose(terrainFile)) {
case Z_OK:
    break;
case Z_STREAM_ERROR:
case Z_ERRNO:
case Z_MEM_ERROR:
case Z_BUF_ERROR:

    throw CTBException("Failed to close file");
}
