In Node Red v0... I saved a copy of my flow with the export function. After a problem with my Raspberry Pi I installed a new version of NR. In NR v1.3.4. I can't get the saved flow back, dozens of errors. I there a conversion necessary?

I have edited that post to show the flow in a proper code block. You should now be able to copy and paste from the post directly.

The flow format has not changed. What sort of errors are you getting?

SyntaxError: Unexpected token } in JSon at pos 169 260,"wires":},{"id.........

Something has corrupted your JSON file. How did you save it? Where you are copy and pasting it from? From the error message we can see a wires property missing its value. 260,"wires":},{"id......... That is a common symptom when people paste their flows into this forum without wrapping it properly as a code block. The markdown parser sees the [] value of the wires property and treats it as a link syntax and strips it out. The question is whether that corruption is in the source file you're copying from, or an artefact of how/where you are copying it from.

The SD card of my RPi failed and I was forced to install all my programs again. Sadly I didn't save the flow on a separate drive and copied the flow from the forum. I understand that I didn't put it correctly on the forum. Now I have to build the flow again and I will save the flows in the correct manner. Thank you for your help.

If you are copying it from the forum, then rather than copy it from the page directly, first click the pencil icon next to the post (maybe hidden behind the ... icon). That will take you to the edit page for the post where you'll see the original content before the markdown formatter is applied.

I tried to copy from the edit page, same errors. My post from 18 jul 2020: Controlling model train. Is it possible for you to open my post?

If you paste a link to it to save me searching - sure.

[image] Controlling model train Share Your Projects Node-Red, Raspberry Pi 4 and 0, Esp32, MQTT. In the last months, a lot of spare time, I build my 40 year old model train set and tried to control it with Node-Red. First step: Manually controlling with the Dashboard. Second step: I build a SVG layout on the screen to mouse-control the turnouts Third step: With the node "finite state machine" it is possible to run a program for the train. If anyone is interested I will publish the code and the hardware in this topic. My excuses for the use…

Success. The build of the SVG layout of the traintracks took a lot of time and sweat. Thank you very much for the help.

Wow! that was super nice of you Nick.
