Problem Description

When an error arises within the application running code, it triggers another error TypeError: sequence item 0: expected str instance, PosixPath found that is reported.

This is caused by not converting PosixPath to str in our error reporting code.

Hello @LeStarch !

I am getting this error when running the fprime-gds for a custom board (SAMV71Q21), application and dictionary. Any idea how to solve it?

This error originates from error handling code. Fixing it in this issue revealed the true error.

You could install the latest GDS.

1. Clone F´ GDS: git clone https://github.com/nasa/fprime-gds
2. Install it: cd fprime-gds; pip install .

This will run the development version where this error is fixed. It will allow reporting of w/e error is tripping this.

@LeStarch Thank you! That fixes the error. I did not know if I had to install the latest version of F prime to solve the bug, but now it is clear.

I am still getting now some errors when trying to run fprime-gds with a custom app with the command I put above:

Note that I am running a devcontainer.json file for VSCode along with a Dockerfile. Do I have to forward ports in the devcontainer.json file as this: // Use 'forwardPorts' to make a list of ports inside the container available locally. "forwardPorts": [5000, 50000, 50050],

and expose the ports in the Dockerfile or neither?

There is not much info on how to use fprime-gds and port forwarding with the fprime-gds tool :/

[LeStarch]

To be clear, you are installing the development version of the GDS tool, not all of F´.

This particular crash is happening in the Ref application. The next thing to do is look in the GDS logs (same directory where you ran GDS there will be a logs sub directory with time/date folders for each run). Look through Ref.log and see why it is stopping early.

It depends on where you are running the GDS. If the GDS is inside the container, then the only port forward you need is 5000 for the browser to connect into the container.

If you are running GDS outside the container, and flight software inside, then it becomes more complicated. It will depend on, which side is the server in the connection.

We should probably move this discussion to a "Discussion" such that it does not get lost within a closed ticket.

Done! I started a discussion in #2770. Thanks!
