hs project dev not supported in v2025.1

[GLopez13]

Hello,

I upgraded my apps from the platform version v2023.2 to the v2025.1, then I'm trying to run the command "npx hs project dev" and even it asked me (as usual) if I want to continue testing in "X" account and select the extension I want to test...it finally "fails" saying "Failed to start local dev server: Unsupported platform version "2025.1" "

I updated my hs cli as well, now I have v7.7.0

Any idea what could be the issue? 

Thank in advance!

Hey @GLopez13 

After reviewing some documentation, there have been some changes since this post. Although it's a minor update, it looks like hubspot cli v7.9.0 and platform v2025.2 were released, have you tried updating to see if that resolved the issue? 

Some other details to check might be your node version:

v2025.1  requires Node v20+
v2025.2 requires Node v22

You might also want to check the the hsproject.json file to see if the platformVersion is referenced properly: 

{
   "name": "my_project",
   "srcDir": "src",
   "platformVersion": "2025.2"
}

And ensure that the cli tool, platform, and dependencies are referencing the correct version on your system.

If possible you could try installing Node globally to see if the issue persists, running "hs project dev" excluding the npx reference. 

Hope this helps!
