can this give us a clue? I'm getting this error:

the "Payload" tab contains the project id info, so it shouldn't be the cause for the delete call fail

How do I check that? I did nothing in the settings other than the recommended defaults in the docs

Can you try checking with a different browser...?

Hi MinuteWalrus85 , sorry, missed this 😞
The error you're showing seems to indicate the WebApp sent a request with no "project" field, which is very strange.
Can you look at the request info for that specific call and share the JSON sent by the WebApp to the server (for which what you've was the response)?

this is an error during training that points out to ElasticSearch error. This might be also the cause of the delete error, what do you think SuccessfulKoala55 ?

(checking now, there are no Load Balancers in this region)

tried both with Firefox and Chrome, results are similar also between computers and OS (ubuntu and Windows)

LEt me try and find what was the reason back when I saw it...

this is what I got:
{"meta":{"id":"7cd78b67e5384e739b9aec6cdc030e6d","trx":"7cd78b67e5384e739b9aec6cdc030e6d","endpoint":{"name":"projects.delete","requested_version":"2.20","actual_version":"1.0"},"result_code":400,"result_subcode":12,"result_msg":"Validation error (error for field 'project'. field is required!)","error_stack":null,"error_data":{}},"data":{}}

What's interesting is that SOMETIMES (rarely) it succeeds

Well, this basically means ES was non-responsive, but the error you described earlier had to do with a missing parameter when a request has reached the server, which is very different...

Any special settings on ELB? I've seen once an ELB stripping payload from HTTP GET calls and producing the same results

Thanks Jake for your help, it's highly appreciated. This is an AWS EC2 running the clearml-server AMI (region of EC2 is us-east-1)

OK, if that's still the error for this call when "project" is in the actual payload, we might have some proxy issue - it might be that someone is dropping the payload along the way - where/how is your server hosted?

Hi MinuteWalrus85 , can you look at the Network section in your browser's Developer Tools (F12) and see the what is reported when you try to delete? I assume one call returns with an error status
