Ok, I got further with the webextension, different error:

{
  "context": [],
  "cause": {
    "details": {
      "code": 7002,
      "when": {
        "t_ms": 1776892399041
      },
      "hint": "Response invalid",
      "requestUrl": "http://localhost:9966/templates/paivana",
      "requestMethod": "GET",
      "httpStatusCode": 200,
      "response": "{\n \"template_contract\": {\n \"choices\": [\n {\n \"amount\": \"KUDOS:1\"\n }\n ],\n \"summary\": \"The summary\",\n \"template_type\": \"paivana\",\n \"website_regex\": \".*\"\n }\n}",
      "validationError": "expected number at (TalerMerchantApi.WalletTemplateDetails).template_contract.minimum_age but got undefined"
    }
  }
}

Will check if 'minimum_age' is a mandatory field...

https://docs.taler.net/core/merchant/get-templates-TEMPLATE_ID.html#get-[-instances-$INSTANCE]-templates-$TEMPLATE_ID clearly states that minimum_age is an optional field.

Sebastian: if you can help fix this quickly, that'd be welcome ;-).

i will give it a try, i don't have a paivana setup but looks like a problem in taler-util

I see that the template interface changed a lot, it won't take me much to sync them up.
That may fix your problem

69b9d14ed..5c3313e86 spec updated.
all spa still doesn't support new template types that validation check is fixed

since template_type is not yet supported is falling into the default

TBH You don't need a template_type in the merchant side if you already have the ID

this is what paivana generates

taler://pay-template/merchant.taler/paivana?session_id=1777063148-8rXGN2Yep-5Bp24VsSD2R4hES9eYZI_LwmSqsvRcluo&fulfillment_url=https%3A%2F%2Fpaivana.taler%2F

but then it fails because of paivana id

curl 'https://merchant.taler/templates/paivana' \
  --data-raw '{"template_type":"paivana","paivana_id":"1777063148-8rXGN2Yep-5Bp24VsSD2R4hES9eYZI_LwmSqsvRcluo","website":"https://paivana.taler/"}'

HTTP/1.1 400 Bad Request

  "hint": "A parameter in the request was malformed. This is likely a bug in the client implementation. Check if you are using the latest available version and/or file a report with the developers.",
