Here i have used Binary JSON called BSON Document, So there are limits to store in MongoDB as per MongoDB Docs:

• The maximum BSON document size is 16 megabytes
• MongoDB supports no more than 100 levels of nesting for BSON documents

What is the other replacement method?

• Definition:

As per MongoDB documentation MongoDB GridFS Docs:

GridFS is a specification for storing and retrieving files that exceed the BSON-document size limit of 16 MB. GridFS does not support multi-document transactions. Instead of storing a file in a single document, GridFS divides the file into parts, or chunks, and stores each chunk as a separate document.

• API Reference:

If you need to implement this is NodeJS then MongoDB has provided Docs, Here is the MongoDB API Reference Docs

• Stack Overflow Reference:

If you need any help in implementation then refer stack overflow post, Here is the Stack Overflow Reference

It turns out that there was a bug in my server program.

I was sending a 'Connection: Keep-Alive' header, and then closing the connection after sending the file.

I now send a 'Connection: Close' header, and everything works perfectly.

Sorry about that.

The problem is solved!

The exception was raised as long as and only while there was another login to the same IMAP-Account on another PC active. It seems that as long as there is more than one login or session simultaneously to the same Email-Account, the exception is raised.

Sorry for disturbing.

Thank you very much for your attention. richard

There is a limitation of a pipe buffer which varies across systems. Mac OS X, for example, uses a capacity of 16384 bytes by default.

You can use this bash script to check your buffer capacity:

Now that I've reviewed your code, I've found the answer. First, a few points:

1. Virtual Assistant is still in Preview and the TypeScript version of it is a lower priority than C#. Expect bugs. Also, there's a better-than-zero chance it's going to change pretty drastically in the future. Personally, I'd use it for ideas, but develop by starting with something like CoreBot and then integrating in the stuff you actually need.
2. I have no idea why adding this.onDialog(this.activityToText.bind(this)); results in a double-welcome message. I think it has to do with point 1.
3. The reason this didn't work is my own fault. I included trim() because it mirrors the C# version of this answer, but it actually breaks it because it doesn't result in a falsy value. Sorry for the confusion and I'll edit my other answers.
4. You don't need turnContext.activity.text = JSON.stringify(turnContext.activity.value); at the end.

I'm going to expand on this because it's an important aspect of Javascript to understand.

When you have:

What you should do is use your setError function to alter the state. As you can see I pass down the setError function to the component down. If you want to go deeper maybe check useContext.

Your addBlock function expects a Block, but you provide 1 in newChain(). Change the line to

The problem is this line:

if (received_message.text) {

When this gets called, received_message which is passed in is undefined, so when you try to get the text field from the received_message variable it will throw an error since received_message is undefined and thus would not have any fields you could call from it. Check to see if received_message is ever set properly before being passed into your handleMessage function.

I think what you are asking for is this?
