How to fix “The specified blobdoes not exist. HTTP Status Code: 404 Error while using Start-AzStorageBlobCopy

Question

I'm getting the error "The specified blob does not exist" running the Start-AzStorageBlobCopy that copies a blob into another new blob in the same folder, the problem looks to be with that destination blob.

$sasKey = 'sv=2019-02-02&ss=b&srt=sco&sp=rwdlac&se=2020-06-07T20:40:57Z&st=2020-01-07T13:40:57Z&spr=https&sig=...'
$storageContext = New-AzStorageContext -StorageAccountName 'my-storage-account' -SasToken $sasKey 
$context = $context.Context
Start-AzStorageBlobCopy `
        -Context $context `
        -SrcContainer 'labo' `
        -SrcBlob 'folder/document.txt' `
        -DestContainer 'labo' `
        -DestBlob 'folder/document2.txt' `
        -Force -Verbose

Just find an error in your script:

$storageContext = New-AzStorageContext -StorageAccountName 'my-storage-account' -SasToken $sasKey 

# Should be $storageContext, not $context
$context = $storageContext .Context

Then, I test with the following script:

$sasKey = '?sv=2019-02-02&ss=bfqt&srt=sco&sp=rwdlacup&se=2020-03-06T10:02:26Z&st=2020-03-06T02:02:26Z&spr=https,http&sig=tj1c***************************D'
$storageContext = New-AzStorageContext -StorageAccountName 'storagetest789' -SasToken $sasKey 
$context = $storageContext.Context
Start-AzStorageBlobCopy `
        -Context $context `
        -SrcContainer 'test' `
        -SrcBlob 'hello/world.json' `
        -DestContainer 'pub' `
        -DestBlob 'hello/world.json' `
        -Force -Verbose

Result:

And, by checking in the storage account, the blob is successfully copied to destination container:
