otCoapSendResponse returns OT_ERROR_PARSE when adding a struct with a uint32_t non-null last element I have a struct defined as:struct sendIP_struct {
char node_type[12];
char description[8];
uint32_t uid;
} msgSendMyIP = { .node_type = NODE_TYPE, .description = NODE_DESCRIPTION, .uid = 0 };I take this struct and append it to a thread response message by calling otMessageAppend with no resulting errors. However, what I noticed is that if I pass this struct with .uid defined as anything but 0, otCoapSendResponse returns OT_ERROR_PARSE. Per RFC 7252, section 5.2.1, I am trying to do a legal "piggybacked" response to a GET request.After further testing, I found that it did work when I changed the last element in the struct from uint32_t to uint64_t.struct sendIP_struct {
char node_type[12];
char description[8];
uint64_t uid;
} msgSendMyIP = { .node_type = NODE_TYPE, .description = NODE_DESCRIPTION, .uid = 0 };I set .uid to a value other than null and it all seemed to wo
