ERROR exporting program from online compiler

I am trying to export a program from the online Compiler but I keep getting a fail error. Please advise.

This issue seems to exist for the HelloMQTT program example (HelloMQTT - Sample MQTT program - simple send and receive | Mbed) . I seem to be able to export other programs.

Export target NUCLEO-L4R5ZI
Exporting toolchain is VSCode-GCC-ARM.

Looking forward to you reply.

Best regards,
