The code is built using Elektron-sdk-1.4.0.L1.linux. It was working fine until this error started showing whenever i try to run the code now. Is there any configuration setting that i need to change in EmaConfig.xml or in the source files to correct this behaviour.
Also i did not mody any files between working and non-working state of the code.

I got the same error when using the channel_3.

However, if I added <CompressionThreshold value="300"/> in the Channel_3, the problem has been solved.

        <Channel>
            <Name value="Channel_3"/>
            <ChannelType value="ChannelType::RSSL_ENCRYPTED"/>
            <CompressionType value="CompressionType::None"/>
            <GuaranteedOutputBuffers value="5000"/>
            <CompressionThreshold value="300"/>
            <!-- EMA discovers a host and a port from EDP-RT service discovery for the specified location 
                 when both of them are not set and the session management is enable. -->
            <Location value="us-east"/>
            <EnableSessionManagement value="1"/>
            <EncryptedProtocolType value="EncryptedProtocolType::RSSL_SOCKET"/>
            <!-- ObjectName is optional: defaulted to ""                                                -->
            <ObjectName value=""/>
        </Channel>

I am using ESDK1.5 on Windows.

@saurav1

From the error, you may use the LZ4 compression type. The compression threshold of the LZ4 compression type must be equal to or greater than 300.

You can change the value of the compression threshold with the following configuration.

<CompressionThreshold value="300"/>

Please add this configuration to the Channel_3 channel in the EmaConfig.xml file. If it doesn't solve the problem, please share your configuration file (EmaConfig.xml).

EmaConfig.txtThis is the configuration i am using. The compression type is set to none in the config.

<CompressionType value="CompressionType::None"/>

If i use LZ4 compression with appropriate threshold as mentioned above i get different errors

Thank you for the help. i modified CompressionType field to LZ4 along with setting threshold, that's why it didn't work earlier.
