[atlas] Error for getting measurement results from an api

Hello,

I would like to use the Ripe api : /api/v2/measurements/{msm_id}/participation-requests/{source_id}/.  for getting measurement results, but I keep getting the following error  (in the picture).

Here is the website of the different apis: https://atlas.ripe.net/docs/api/v2/reference/#!/measurements/Type_0_1_2_3_4_5_6_7_8_9_10_11_12_13_14_15_16_17_18_19_20_21_22_23_24_25

Is it due to my key? Knowing that I have already used it to create measurements and get measurement results and in other apis from Ripe.

Concerning the example below, I have checked the measurement ID and that the probe in the source ID figures among the participant probes. 

I don't quiet see the source of the problem, do you have any ideas about this?

Thank you,

Cheers,


Sanaa
