Has anyone experienced problems with their N8n workflows hosted on Railway? They work initially, then stop running. The explanation given is that the workflows were created with older versions of N8n, and supposedly there are extra equal signs (=) in the URLs or JSON that are halting the flow. The strange thing is that they were working fine before. Then the solution is to recreate them from scratch to eliminate the error, and after recreating them, they crash again. You check them, and again they claim it's contaminated with older N8n versions. Has anyone actually found the root cause of this problem and how to fix it?

Also, when I share workflows, they encounter problems... they don't execute. Is this a Railway issue? I would appreciate any insight into this, as it's preventing the created workflows from running.
