Gmail Addon - cannot open external links even tho they are defined in the allowlist

This started happening lately. In FireFox, the links are opening ok, but in Chrome/Safari, after a quick loading sign, nothing happens. In the console I see an error: Refused to execute a script because its hash, its nonce, or 'unsafe-inline' does not appear in the script-src directive of the Content Security Policy.

Addon is written in Apps Script.

Example code that stopped working:

CardService.newActionResponseBuilder()
    .setOpenLink(
      CardService.newOpenLink().setUrl("https://sub.fulldomain.com/foo")
    )
    .build()

In the manifest:

...
"addOns": {
    "common": {
      "openLinkUrlPrefixes": [
        "https://sub.fulldomain.com/"
      ],
...
}

Based on the info in the docs, that should have worked. Also tried defining a wildcard "https://*.fulldomain.com/" and tried to define a full path. Still nothing works.

Update

Looks like the code that stopped working is specifically setOnClickOpenLinkAction that calls an action that builds the url to be open:

// In file X I build the card
const button = CardService.newTextButton()
    .setText("click here")
    .setTextButtonStyle(CardService.TextButtonStyle.FILLED)
    .setOnClickOpenLinkAction(
      CardService.newAction()
        .setFunctionName("openLink")
        .setParameters({ ...ourParams })
    );

// ...

// In main I have the "openLink" function
export function openLink(event): ActionResponse {
  const url = buildUrl(event.parameters);

  return CardService.newActionResponseBuilder()
    .setOpenLink(CardService.newOpenLink().setUrl(url))
    .build();
}

Followed this example.

Question

How to make setOnClickOpenLinkAction work?

Workaround

The only workaround that worked for me, was to use setOpenLink directly on the button:

const button = CardService.newTextButton()
    .setText("click here")
    .setTextButtonStyle(CardService.TextButtonStyle.FILLED)
    .setOpenLink(CardService.newOpenLink().setUrl(url))

My question is still the same tho, how to make setOnClickOpenLinkAction work?
