Failed to parse XML file. Error: Failed to parse XML file. File is too long. Length = xxxxxxx. Max. permitted length in bytes is 15360000Issue Discovery can fail with the following error message in the pattern logs: Failed to parse XML file. Error: Failed to parse XML file. File is too long. Length = xxxxxxxxxxx. Max. permitted length in bytes is 15360000ReleaseAll release.CauseIn this case, the payload seems to be larger than the default permitted size in bytes of 15360000.There is a way to increase the value. On each of the MID Server record, under the "Configuration Parameter", there is this config name "mid.xml_parsing.max_file_size". The default is 15000.The value will be multiplied by 1024.And hence the default value equals to 15000 * 1024 = 15360000ResolutionOn each of the MID Server record, under the "Configuration Parameter", there is this config name "mid.xml_parsing.max_file_size". The default is 15000. We can increase this to resolve the issue.Related LinksNote: The fact that the payload is coming back too large, could be a sign of an issue.I think the best long-term approach, might be is to review why it is returning such a big payload.
