What problem was encountered?

NPE in BlockBlobClient.exists

Have you found a mitigation/solution?

Kind of - i actually go to this from getBlobOutputStream, so passing overwrite=true fixed the issue for me

Caused by: java.lang.NullPointerException at com.azure.storage.blob.specialized.BlobClientBase.exists(BlobClientBase.java:405) at com.azure.storage.blob.specialized.BlockBlobClient.getBlobOutputStream(BlockBlobClient.java:148) at com.azure.storage.blob.specialized.BlockBlobClient.getBlobOutputStream(BlockBlobClient.java:132) ... 70 more

From debugging existsWithResponse(null, Context.NONE) -> returns null Then call to existsWithResponse(null, Context.NONE).getValue() -> is NPE The blob shouldnt exist at that point btw
