Deploy failing. No response from server (node:function)

General

Hey

I got a strange behavior with node Red.

I installed version node Red v1.3.5 with Node JS 14.16 on 3 PCs.

On one PC I cant update function blocks!

I already testet the following: I closed node Red and then startet. Then I created a new flow (without projects=true). I added a inject and a debug and deployed. This worked fine.

As soon as I add a simple function block and add "msg.info=1;" to the function code, everytime I push "Deploy" the error is shown by the browser.

Here is the detailed log of node RED:

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

Only by restarting node RED I can continue working (but I cant deploy the code to the function).
If I Import a flow from another pc (with functions), the flow itself runs fine.

Do you have any idea?

If I open Chrome Debug (CTRL+SHIFT+C) and go to console I find this POST:

I "fixed" this by deactivating user password in settings.js on this test case, but after using bigger blocks, I get similar behaviour:

It looks like a issue with certificates of node RED ... If I export the flow to clipboard, then close the broswer and then reopen node RED, i can import from Clipboard and then apply.

Any idea what's going wrong?

How have you configured https in the settings file? As you say, looks like a certificate issue.
