Hi Raj,
The error message indicates that the code generator cannot generate code the function “jsonencode”.
You may work around this error by manually implementing the function “jsonencode” as a custom MATLAB code that is supported for code generation or as a C/C++ code. If you implement the functionality in C/C++, you may call it from inside your MATLAB code using “coder.ceval”, before generating code as usual. Here is a third-party implementation of “jsonencode” from MATLAB File Exchange that might help:
You may read more about this issue along with possible workarounds in the documentation:
I hope it helps!
