FMIKit 3.1 ME-FMU generation error Matlab 2020b (working with FMIKit 3.0) (RTWSFCN)

[AndreasHofmann217]

Trying to generate a simple input -> gainblock -> output ME-FMU using Matlab/Simulink 2020b fails.
Error rises from CreateSimStructForFMI as mdlInfoSLSIze is not part of S->blkInfo.blkInfo2 respectively _ssBlkInfo2 struct in simstrc_def.h.

SimStruct` *CreateSimStructForFMI(const char* instanceName)
{	SimStruct *S = (SimStruct*)calloc(1, sizeof(SimStruct));

	if (S == NULL) {
		return NULL;
	}
	
	S->mdlInfo = (struct _ssMdlInfo*)calloc(1, sizeof(struct _ssMdlInfo));
	
	if (S->mdlInfo == NULL) {
		return NULL;
	}

	S->blkInfo.blkInfo2 = (struct _ssBlkInfo2*)calloc(1, sizeof(struct _ssBlkInfo2));

	if (S->blkInfo.blkInfo2 == NULL) {
		return NULL;
	}

	S->blkInfo.blkInfo2->mdlInfoSLSize = (struct _ssMdlInfoSLSize*)calloc(1, sizeof(struct _ssMdlInfoSLSize));

	if (S->blkInfo.blkInfo2->mdlInfoSLSize == NULL) {
		return NULL;
	}

	_ssSetRootSS(S, S);
...

Model does work fine with FMIKit 3.0 and Matlab/Simulink 2020b as the part is missing

SimStruct *CreateSimStructForFMI(const char* instanceName)
{
	SimStruct *S = (SimStruct*)calloc(1, sizeof(SimStruct));
	if (S == NULL) {
		return NULL;
	}
	S->mdlInfo = (struct _ssMdlInfo*)calloc(1, sizeof(struct _ssMdlInfo));
	if (S->mdlInfo == NULL) {
		return NULL;
	}

	_ssSetRootSS(S, S);
...

Not an issue for my application, since FMIKit 3.0 should be good enough. Wanted to give feedback anyways.

Best regards,
Andreas

I have the same issue only in Matlab 2021a
