send e-mail upon completion of request (https://staging.odahub.fr/mmoda/)

[andriineronov]

The frontend (or the dispatcher?) sends an e-mail upon submission of request, which is useful particularly for the Fermi/LAT service, where the requests can be long. However, the initial e-mail promises that I will get a new e-mail upon completion of the request. This second e-mail never comes..... Is this a bug (the behaviour observed at https://staging.odahub.fr/mmoda/)

I have also recently noticed the missing of some done emails, but in very specific cases. I am investigating what the reason could be

[dsavchenko]

I think I never got the completion emails when requesting nb2workflow products
What could be specific about this type of requests?

[burnout87]

It should not be related to the type of request and products, rather to a number of other conditions related to the configuration and the fields of the token

[dsavchenko]

This issue persists for French staging. Do we have any updates/progress on it?

[burnout87]

I kept noticing the same behavior

[volodymyrss]

in unige probably message queue piled up

[volodymyrss]

this has to do with message passing on the nb2workflow backend

[dsavchenko]

This issue was due to

1. dispatcher config option email_sending_timeout_default_threshold was set to large number
2. better url validation regex oda_api#220

Therefore, I close this one, as it is specific to https://staging.odahub.fr/mmoda

@burnout87 still notices email sending problems sometimes with other instances. Probably we need a separate issue then

thanks for updating!

This issue was due to

1. dispatcher config option `email_sending_timeout_default_threshold` was set to large number

2. [better url validation regex oda_api#220](https://github.com/oda-hub/oda_api/pull/220)

Therefore, I close this one, as it is specific to https://staging.odahub.fr/mmoda

Here we decided to use inspect endpoint to investigate the cause. @burnout87 please follow-up in another issue

I note, however, that at the moment, https://staging.odahub.fr/mmoda/ fails to process callback and does not nominally complete any nb workflow. Since we use it for testing, it's important to have it live soon.

I just tried, and it was successfully able to reach the 'ready' state. So this issue is resolved there.

However, sometimes I notice the behavior when one of the POST requests which frontend sends to dispatcher ends up with 504: gateway timeout. In this case, there are no visible consequences, frontend just continues to show submitted state, but doesn't send any requests anymore.
This could be improved both in frontend, but we also need to investigate, what causes these timeouts.
